Output volume does not match vol control value

[igorzwx]

It seems that you are using a problematic soundcard:

05:06.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01)

It might be a bug in the driver.

Open Sound System v4.2 build 2005 has been announced for Linux (x86/amd64), Solaris (x86, amd64, sparc), FreeBSD 8 (x86, amd64), UnixWare, and Open Server.
* Added support for Envy24HT PCIe
viewtopic.php?f=19&t=4391

Perhaps, Cesium may explain the problem.

EDIT: You may try the pcm slider.

Another option is to disable vmix (it is a kind of PulseAudio).
It is very probable that your soundcard has HW mixer. In this case, you do not need vmix.

[hemebond]

Disabling vmix didn't help. I think there was a reason I was adjusting the master volume instead of PCM; possibly different apps or sinks not using PCM? I can't remember now. I'll try and switch to using PCM for now. Let me know if there's any more info you want.

Yes, PCM is a problem, especially if you are using Sennheiser headphones for audiophiles.
Some apps may rise PCM volume, and you may get a very loud sound to the headphones (this may damage your hearing!!!)
You should always check ossxmix and set volumes to minimum before using headphones for audiophiles.

If you have problems with osstest (stereo, left/right), you may try to plug/unplug your headset or speakers.
Sometimes, it helps to fix the problem, if it is caused by "jack-sensing" .

Well, turns out my sound is even more broken now, with Adobe Flash now blocking any other application from using audio. Looks like I'll have to reinstall my OS sooner than I'd like.

It might be sufficient to correct settings in ossxmix and/or re-install OSS4.
If you do not know how to re-install OSS4 correctly, you may study this "howto" viewtopic.php?f=3&t=3543&start=30#p15711
You may train this on Arch Linux LiveCD (Archiso-live or CTKArch) viewtopic.php?f=3&t=3933#p17316

Thanks, but I think I'll leave it. It at still works for most things (my microphone has also stopped working), so I'll just install a new OS when I get time. Thanks for your help.

Pulse Audio doesn't see/list any recording or input devices.

Your mic is set to 0 in the mixer. That is why your mic does not work.

Code: Select all

mic <monovol> (currently 0)

To have mic working, you need these:

Code: Select all

mic <monovol> (currently 70)
mic.rec ON|OFF (currently ON)
igain [<leftvol>:<rightvol>] (currently 60:60)

vmix is also disabled:

Code: Select all

vmix0-enable ON|OFF (currently OFF)

That is why "Adobe Flash is blocking any other application from using audio".

You may want to set "mono" to 0 (you may not need it):

Code: Select all

mono <monovol> (currently 50)

Your mic is set to 0 in the mixer. That is why your mic does not work.

Code: Select all

mic <monovol> (currently 0)

That property controls the volume of output from the speakers. If I put that up the sound going into my mic is output from my speakers. Didn't help recording.

vmix is also disabled:

Code: Select all

vmix0-enable ON|OFF (currently OFF)

That is why "Adobe Flash is blocking any other application from using audio".

This was the issue. I disabled it earlier in this thread. Now I see a recording device in Pulse Audio.

Thank you again.

This is very strange. My mic controls are exactly these ones:

Perhaps, something wrong with your PulseAudio settings.
If you have two "PulseAudios" installed (vmix and PulseAudio), it might be difficult to configure them correctly.
One of them might be sufficient, the other might be removed.

FYI, I installed Debian this week, I'm back to ALSA/PA, and the audio problem is terrible. Volume controls doing their own thing, distortion, stuttering. *despair*
