Those higher than CD quality are unlikely to yield any benefit to all
but very hifi-oriented people (and _I_ think not even most of those, in
blind tests), at the expense of much bigger files.

One of the audio capabilities in PC audio, is to loop
the material being played to the speakers, back to an
ADC on the input side. This is termed "What You Hear"
or "Stereo Mix". On Win10, this is a "Disabled" item, and
Microsoft makes you bob for apples to find it and switch
it on. It's considered a DRM-thwarting path, which is
why the bums switch it off and try to hide it.

Line-In ---
\
Mic-In --- -- ADC DAC ---+-- (Amp)--- LineOut
/ |
Stereo Mix +-- |
| |
+---------------------------+

That shouldn't be a useful option in your current situation,
as you are taking audio from another input side source
(Mic In or Line In) and playing that to speakers.

As for the device sensing and operational adjustments
the phone is making, I don't know what capabilities they
think they have on phones.

*******

On PC audio, you can attempt to sense the difference
between a "Line Level Input", which has a defacto
standard input impedance of 10K ohms. Or the other
option is 32 ohm headphones. Sound chips have a power
amp on the output, which is "switchable". If a 32 ohm
headset is detected, a CMOS power amp drives that. And
puts up to 1V amplitude on it. The power amp has a
roughly 1 ohm output impedance (it is "stiff" in
electronics parlance, and is a "voltage source"
or close to it). Because the value is finite, it
implies there isn't closed loop feedback around
the power stage, to make the effective impedance
even lower.

Now, what we don't know, is the overload behavior
of that amplification stage. It's known that the
amplification stage, when used, degrades the SNR by
10dB. So it's not always the best choice for audiophile
recording purposes. But you do get the benefit of
higher drive, if you tell a device "drive my headphones".

The other case, is with the amplifier stage switched off.
Well, there's still an amplifier, but it's around 600 ohm
drive. A 600 ohm, line level (1volt) output, still
nicely drives a 10K input on another piece of stereo
recording equipment or drives the Line In on the computer.

When driving Zalman 5.1 headphones, there are like
six speakers inside the oversized headphones. This
requires three stereo pairs of amps at 32 ohms.
What happens is, if you plug those into an HDAudio
on a computer (three 1/8" plugs), the FrontLeft/FrontRight
work fine at 32 ohms. However, the other four channels
of sound won't switch on their amps. The other four channels
are driven at 600 ohms, and the channels in question
are "weak" and you can barely hear them. What we
learn from this, is the sound chip is not willing
to switch on the amps on *all* channels, even if
it happens to sense that they need it.

How many weird sounds can you get from audio equipment ?

Well, there's the "motor boat sound", a kind of put-put-put
that comes from an overloaded op-amp. Typically this comes
from driving a pure capacitive load, without a series
resistor between the opamp and capacitor, to "adjust"
the closed loop behavior of the amplifying circuit.
The outputs on computer sound, are capacitively coupled,
but that is a *series* capacitor, not a capacitor to ground.
However, if you connect a heavy enough load (a short
circuit to ground), then the series capacitor is now
a parallel capacitor to ground. And it would be
expected that the output would make the put-put sound.

That's the only behavior I know of, that makes a peculiar
sound effect. The effect might range from, say, 1Hz to 100Hz.

One of my fellow engineers discovered this one day,
and said "hey, come over and look at this".
And I took a look at his schematic, and see this
big-ass capacitor to ground, on the output of an
opamp. And my response was "you can't do that...".
And dug up an applications note, with the proposed
solution to moving the resulting pole so that
the closed loop wouldn't oscillate. I have fallen
into this "moar capacitor equals better performance"
trap my own self, as a hobbyist, and that's why I
knew what to look for :-/ The best learning
is from your own train wrecks.

Just about every audio amp circuit I ever built,
oscillated, with the most comical one being the
amp that oscillated at 500KHz and I could only
see it on an oscilloscope at school (i.e. you can't hear it,
but you can tell something is wrong because the
amp sounds "weird" and "hollow").

There are still a lot of older cars on the road which don't have Bluetooth.
Like mine, a Mazda coincidentally, and I just use the audio jack with my
phone. Works flawlessly. No need for a pairing dance.

Well, at first we were talking about connecting to a PC; micky had
trouble making that work reliably, and an analogue connection gave funny
noises. Someone said maybe the 'phone detects what is connected to it
and behaves differently; I suggested, in effect, that he "fool" it using
a splitter, and that apparently worked.

So in the case of your car/phone combination, it looks as if either
_your_ 'phone _doesn't_ sense what's connected and change its behaviour
accordingly, or your car's input jack looks sufficiently like earphones
that the 'phone thinks that's what it is connected to.

That's what I use in the US, with my 2005 Solara. It works pretty darn
well. I brought two versions of that with me, and I could switch to
one of them**, but I'm having fun trying to make the aux jack work.
Also, if I use one of them, I think I give up the use of the microphone
that is built into the roof of the car, which is very likely better than
the one*** in one of these adapters and might be better than the one in
the phone. But I don't give up the car speakers.

***Because I've tried talking into that in the USA and I'm told it
doesn't sound good. I had hoped I'd left the clear vinyl sheet
covering the hole for the mike, but if I had, taking it off didn't help.
Of course almost no one calls me when I'm in the car. I just like
fiddling with it.

**Both have an aux jack and a USB jack, and a means for answering the
phone. And the Aux jack probably works with the phone. After all, it
was designed to and it shouldn't matter what kind of car is being
driven.

Yes, that's what I did for the first 2 or 3 days, but then it stopped
working. I don't know what year the car is, and I've looked (I still
have to see if there is a registration paper in the glove box.) but it's
only got 15,000 miles on it, as a rental, so I suppose it's a 2019 or
18. It does have bluetooth but it took me 4 or 5 tries to get that
connected.

But JP, I spoke too soon about the splitter and the earbuds. It had
quite a bit of static that way, even if the phone wasn't playing
anything.

I also found a more recent audio driver on the Dell page, installed
that, and it was applied only after I restarted windows. Now great, it
has a setting for Line-in vs. Mike. It's called IDT Audio Control
Panel, but no matter what settings I use, nothing from the phone comes
out through the PC. Until finally it crashed and it went back to the
staticky output.

I went to the control panel and restarted the Audio Control Panel and
though it came up on the screen, the sound didn't change, until I went
to where it was set to Mic and I changed that to Line-in. Then t he
sound disappeared, and changing it back to Mic didn't get the sound
back. Finally Closing the Audio Control Panel did nothing for a 3 or 4
minutes until it went back to the scratchy output.. Well that worked
the first time but this time I have no sound and the Microphone Line-in
part of Sounds/Recording is listed as Not Available.


I want to read my mail and go out, and I want to try the splitter in
the car

Well, it's almost certain that my PC, a Latitude E4300, has a built in
Bluetooth receiver, but I couldn't get it to work so I bought another
for $12. A tiny rectangle that plugs into USB.

This one had a CD with drivers, unlike the ones that cost $1.50 from
China (one of which did work, and which might have worked here.)

It installed but there was still one nasty message about making the PC
discoverable, and when I tried to check that box and save, that part of
the system would crash. But I waited a week and now I can't even find
that screen (One does have to be paying attention to the little cream
colored bubble on the bottom which you must click, twice, one time after
another, to get it to pair, or even the step before pairing.)

And Bluetooth is working...except much of the time the sound is choppy,
clipped at the end of words. Plus 6 of the 7 functions installed
correctly but CSRBtPort_Enumerated_Device-00 did not. It "failed", and
it has a yellow triangle with an exclamation mark in Device Manager,
where it says to Click Update Driver, but when I do that it can't find a
better one. Nor does Troubleshooter or Other Troubleshooters.

I think here is a case where win10 might work better??

To some extent, it depends on what's playing whether the words are
clipped or not. Maybe later or with a different station, it will work
better.


This is about win7 and win10, so posted both places.

My android phone has a couple radio apps that are better** than any PC
programs

I've paired my phone with my win10 desktop and I've been trying to pair
my phone with my win7 laptop, and I want to take the sound that comes
out of the phone apps and play them through the better, louder speakers
of the PC. (Better and louder than the phone) Just like I do with the
car.

But "everyone" does this with a car and for the most part, people don't
do this with a phone and a PC, laptop or desktop.

Is there a PC program that will accept bluetooth transmission and play
them. Or a program that willl accept bluetooth transmissions and make
them appear to be coming from a CD drive.

For example, VLC has a lot of possible inputs, including Open Media:
File, Disk**, Network, Capture Device.

It has playing, streaming, converting, and queuing. Streaming would
work if I could make it point to the bluetooth (or a usb cable??, but
USB cables don't play audio from phones do they, only files as files.)

**Including Blu-Ray, which for a second I thought was Bluetooth.
**Only marginally better than RadioMaximus but still better in a couple
little ways, and as I'm learnign to how to play exactly what I want in
the car, I'd like to be able to play things the same way at home.

How does your Latitude play sound directly from your hard-drive? My
Latitude 610 running 32-bit XP was never very good even at that simple
task, over WiFi it could be unlistenable.

of the PC. (Better and louder than the phone) Just like I do with the
car.

But "everyone" does this with a car and for the most part, people don't
do this with a phone and a PC, laptop or desktop.

Is there a PC program that will accept bluetooth transmission and play
them. Or a program that willl accept bluetooth transmissions and make
them appear to be coming from a CD drive.

For example, VLC has a lot of possible inputs, including Open Media:
File, Disk**, Network, Capture Device.

It has playing, streaming, converting, and queuing. Streaming would
work if I could make it point to the bluetooth (or a usb cable??, but
USB cables don't play audio from phones do they, only files as files.)

**Including Blu-Ray, which for a second I thought was Bluetooth.
**Only marginally better than RadioMaximus but still better in a couple
little ways, and as I'm learnign to how to play exactly what I want in
the car, I'd like to be able to play things the same way at home.



I could find a reference to two kinds of audio protocol stacks being available.

The workaround seems to be to stream music, a podcast, etc. at all times
while using bluetooth with Waze. At least for iOS devices, this seems to
force the Waze instructions to be sent via A2DP.

If no other audio streams are running, then Waze announcements seem to
go via HFP (hands free protocol, also used for phone calls). That's when
the trouble starts. Instead of "in 2 miles turn right onto XXXX lane",
you get "turn right onto XXXX lane". Often followed by some kind of
"phone call completed" notification.

Using an audio player application, could you load up an audio
which is "silence" or 0V all the time, and play that back as
a bias to keep the channel open ? Maybe that will force the
beast to use A2DP continuous, when the two applications and
their audio streams are mixed together ?

And you can do that as a verification the audio channel
works first. Try an audio player, and send a continuous audio
stream, and see if any clipping occurs.

I think you are making this way more difficult than it needs to
be. Try this from a browser on your desktop:

https://tunein.com/radio/local/

Neither a phone or Bluetooth is needed to select and play any of
your local FM stations and all are listed on one page.

Later it said specifically to reinstall the driver, but Reinstall did
not work, so I uninstalled and re-installed, but it the problem was the
same when I was done.

How does your Latitude play sound directly from your hard-drive? My


Just fine, allthough I can't remember doing that, so maybe I should
check. Wait, I do play radio stations and recordings of old time radio
and they sound just fine.

Latitude 610 running 32-bit XP was never very good even at that simple
task, over WiFi it could be unlistenable.


Some parts of the show seem to come through better than other, between
1) quite annoying and 2) just barely noticeable, not annoying at all.

I'll try some other apps and stations. But I'm making progress and
that's what counts.

Use a bluetooth speaker.

That doesn't answer micky's question. Maybe he has good speakers on his
computer, and/or doesn't have a bluetooth one.

Hadrian's Wall has never been a border between Scotland and England. It lies
entirely within England but, when it was built in AD 122 by the Romans as a
defence against the raiding Picts, the future English were still in Germany
and the Scottish were still in Ireland.
