New Mobo, Speaker problem
New GigaByte Z87X mobo with RelTek HD audio Manager.
Have installed, then re-installed audio drivers from GigaByte. - Set RealTek HD Audio Manager to "Speakers". - Maximize volume - Note that analog back panel highlights receptacle that amplified speakers are plugged in to. - Turn amplified speakers' amplifier up to max - giving a low-level of white noise. - Note that varying Windows' volume control has no effect on level of white noise. - Un-plug amplified speakers and note that white nose goes away. - Plug amplified speakers into the same port on another PC, play some music, and they work a-ok. - Plug amplified speakers back into problem PC - Open up Speakers | Sounds | Program Events - Choose a sound. - Click "Test", and the white noise stops for the duration of the sound, but no sound comes out of speakers. I'm doing something dumb.... but what? -- Pete Cresswell |

I'm doing something dumb.... but what? Did you move the OS from an old system to a new system ? Both with RealTek audio, but with different HDAudio ? I suspect something like that happened here. https://www.sevenforums.com/sound-au...-no-sound.html And you probably don't have a "mute" asserted or something. ******* I had a strange case once, where one audio product, the driver *erased* a key registry setting the other audio driver relied on. It took Process Monitor, and skimming through a 100,000 event log, until I spotted a suspicious entry the driver was checking for, and it was not present (as seen in the log). Finding stuff like that is pure lucky, due to the needle-in-haystack nature of that kind of analysis. ******* There are two methods of sensing a speaker connection. (Note - I don't think this has anything to do with your problem.) RealTek uses what's in the spec, which is jack side contacts. So for a RealTek codec to know a speaker is plugged in, the 1/8" plug depresses a switch inside the jack. That's how it knows "something is there", but not what is there. If driving 32ohm headphones on Lineout, the driver needs to enable the "boost", which is ready to drive 32 ohm loads up to 1 volt. Without boost enabled, the noise floor is 10dB lower (that's good), but the output is only in the 600 ohm range. And perhaps not enough to drive headphones. In the case of driving amplified speakers, the speaker input is 10K ohms, and either boost or no boost, will work an amplified speaker. So with RealTek, some fiddling is required. ******* Analog Devices (SoundMax people) invented an actual impedance measurement technique. They place a 25KHz test signal on the port (only your dog can hear that), and since all inputs and outputs are capacitively coupled, their scheme has to measure the AC current that flows, when an AC stimulus is applied. This is how a SoundMax product knows a 10K load is connected, or a 32 ohm load is connected. Their "Wizard" will still ask for confirmation, because obviously a user can connect some piece of junk to the box which fools the sensing. As far as I know, that's not in the spec for HDAudio, and they would have a patent on it. ******* For RealTek front panel audio, the computer case cabling could have "AC'97 wiring" or "HDAudio wiring". The alternatives exist, if the two front jacks have been equipped with the side contact switch thing. On RealTek, if you connect HDAudio-type front wiring, there is a hidden tick box to ask the CODEC to check the resistor ladder for those front ports. Then, the RealTek can sense a plugged in device. If you use older wiring, which lacks side contacts, and you use RealTek, it has no way to tell something is connected. Whether you tick the hidden box or not, won't help, because AC'97 wiring doesn't have any pins assigned for the side contact wiring. So that's a quick overview. In your case, I feel this is an "ancient driver" issue, and perhaps uninstalling the RealTek from Programs and Features, and installing a new one, might help. Other than that, I don't have any suggested directions. I'm sure you've checked the "default" tick box on playback, and it's really set to the lineout speakers. The ancient driver could be messing with port assignments, and maybe the sound is coming out on another jack. Paul |

I'm doing something dumb.... but what? Don't know which version of Realtek's HD Audio Manager program you are using. I have it show an icon in the system tray (but configured to hide into the expanded view of the tray icon). I double-click on that tray icon to show the Realtek HD Audio Manager. That is the RAVCpl64.exe process in Task Manager's Applications tab. It is found under C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe. I have the 64-bit version of Windows 7 Home Edition x64 SP-1. You never mentioned which bitwidth of the OS that you have. The program does not let you see what version it is. That's why I needed the filename so I could right-click on it to look at Properties - Details. I only have 2 front speakers (no rear, center, or bass [which is taken care of by the Altec speakers themselves]). Under its Speaker Configuration tab, I have "stereo" selected for Speaker Configuration selection because I only connect to the stereo output - with the backpanel display in the program shows as the green-colored jack (it is bold, the others are grayed out). Also, "Full-range Speakers" is enabled for "Front left and right" (the "Surround speakers" selection is grayed out because I only have the 2 front speakers). In the program itself, clicking on the "i" information button says: Audio driver version: 6.0.1.5898 DirectX version: 11.0 Audio Controller: HD Audio Audio Codec: ALC888S Some or all of that would be different because you have different hardware than do I. When I right-click on the RAVCpl64.exe and go to Properties - Details, both file and product versions are 1.0.0.386. Neither in the Realtek program, its tray icon, or the Windows volume tray icon are the speakers shown as muted. The white noise is likely due to EMF induced into the chassis and ground plane of the mobo from A/C power line or radio. When your speakers get a signal, even a tiny one enough for it to detect there is a signal, it probably uses some filtering to improve the quality of sound. So the noise from the speakers goes away when you attempt to play some sound. That tool only configures how the driver will tell the hardware on the motherboard to be configured, not what Windows will use to where it sends its audio output. Right-click on the Windows volume tray icon and select Volume Mixer. Are either speakers or system sounds shown muted? Right-click on the volume tray icon again and choose Volume Control Options. Is the "All devices currently playing sound" option enabled? Right-click on the volume tray icon again and pick Playback devices. Windows differentiates between which "devices" (defined in the registry) are used for playback and which are used for recording. That brings up the Sound applet (same if you go into Control Panel - Sound). For me with my 2 speaker setup, and with the Playback tab selected, I scroll down to find the Speakers device selected for output. It is also selected as the default playback device. With it select, click on Properties. Under the Levels tab, the Realtek HD Audio Output slider is set at 40% which is also what the Windows volume tray icon shows, and not muted. The other controls shown are for inputs. Two are disabled (microphone - rear jack, front mic) and one is enabled (line-in). Since I'm not using them, I could mute them, event the line-in jack. Back in the Sound applet under its Playback tab and with the Speakers device selected, I click on Configure. That gives me the test wizard and maybe what you used. Since I only have 2 speakers (front), Audio Channels is set to "Stereo". I click on the Test button and hear the down-chime tone in the left speaker followed by the up-chime tone in the right speaker. I click Next and see the full-range setting. Despite seeing it enabled in another view, it is deselected here. I can enable or disable it, click on a speaker to test, but hear no difference. Alas, they play a mid-range chime tone without any bass so I won't be able to tell the difference. Clicking Next just brings me to a summary screen where I click Finish. While you might have the Realtek tool properly configured for the hardware how you want to use it, you still need to tell Windows which device you want it to use for playback and recording. Under Sound - Playback, I have 6 digital audio devices defined, 2 "speaker" devices defined (one shown with an RCA coax cord but I'm not using the coax jack and another as a speaker icon and that one is selected as the default playback device), another digital device (probably the optical output), and an HDMI device (not using that jack, either). If you have a mic or might later get one, go under the Recording tab and make sure one of those inputs is selected as the default. |

Per Paul:
Did you move the OS from an old system to a new system ? Both with RealTek audio, but with different HDAudio ? No: clean install from scratch... but I'll start reading the link. -- Pete Cresswell |

Per T:
If you are not muted somewhere, your default audio program may be your HDMI (digital) system and not your regular Audio system. I see this a lot. That sounds promising - since I had the bright ideal of retiring my DVI cable in favor of an HDMI cable for one of my monitors. Can you give some more context? I looked into "Windows 7 default programs" but that's on a higher level - like whether to use Windows Media Player or VLC to renter an audio recording. Control Panel | Sound | Playback isn't showing me anything unexpected. I've got "Speakers Realtex High Definition Audio Default Device" selected and the owher three choices a - PA248 Intel Display Audio (that's one of my monitors) - Realtek Digital Output (the speakers are analog) - Realtek Digital Output (Optical): there's an Optical port on the mobo, but I am not using it) -- Pete Cresswell |

Which one is set to your default? Also, when in that dialog, grub around looking for and volume controls set to off or mute. |

I'm doing something dumb.... but what? Hi Pete, Not to ask too stupid a question, but do you have the speaker plug in the right hole? It is typically the green hole, but not always. I have seen it be the black hole. 1) pull out the plug and press the end with your hand. If your speakers are working, they will buzz (60 cycle hum) 2) start something playing. Place the speaker plug in all the holes, until something makes sound. -T |
