Open Sound System

(ossinfo -v3 attached)
When I move jack volume control in ossxmix, nothing changes. And after restarting ossxmix jack controls sets to previous position.
Other controls works ok, jack muting also works.

This simply means that you are out of luck.

The problem is that "oss_hdaudio" is not a real driver. It is a kind of "generic ersatz driver" http://manuals.opensound.com/usersguide ... audio.html

In general Azalia based systems (laptops/motherboards) would require a custom driver to work properly http://manuals.opensound.com/usersguide ... audio.html

Such custom drivers for HDA codecs/motherboards are not available for OSS4 and ALSA.

Since the producers of motherboards are allowed to connect HDA codecs to motherboards how they want, the users of OSS4/PulseALSA may often experience "audio problems".

Perhaps, you may provide some info about your hardware.

Sure. Audio device [0403]: NVIDIA Corporation MCP55 High Definition Audio [10de:0371] (rev a2)
(mainboard: MSI K9N Platinum, sound chip built in)
ALSA could work fine, I don't remember if it so.

You may easily find all sorts of "bug reports" with Google: http://www.google.com/search?hl=en-US&q ... ev%20a2%29

Perhaps, "subsystem" is also needed to identify the thing:

Code: Select all

$ lspci -vnn

It looks like you have Realtek ALC889A codec (or something of the sort) http://www.alsa-project.org/pipermail/a ... 24345.html
But it seems to be misidentified as "ALC883", according to your "ossinfo -v3".

Try also:

Code: Select all

$ dmesg | grep oss_hdaudio

It may say something about "unknown codec", or "HDA codec ... not known yet".

dmesg/grep is empty, lspci attached.

Yes, it should be ALC889A, as I remember.

This seems to be a usual problems. There are many examples with patches on the forum.
You may try to patch it yourself.

There is also a magic tool with which you can create your own "custom mixer driver".

However codecs are different. To make things even worse motherboard
manufacturers have complete freedom to decide which I/O pin they connect
the jacks and other audio inputs and outputs. It is not enough to write
just one mixer driver for each codec. This needs to be done by hand for
every single motherboard (unless there are boards that have the pins
assigned in the same way).
The mixgen.c can be used to create a skeleton of a mixer driver. Then
the result can be fine tuned by using trial and error approach.

In a word, Intel HDA codecs are capable of HW mixing (as well as Intel AC'97 Audio Codecs), although, of course, it may not always work with buggy "generic ersatz drivers" for OSS4, ALSA, or Windows.

For example, ALC887 does support HW mixing with OSS4.

Code: Select all

$ ossmix
Selected mixer 0/High Definition Audio ALC887

$ lspci -vnn
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
   Subsystem: Giga-byte Technology Device [1458:a002]
   Flags: bus master, fast devsel, latency 0, IRQ 22
   Memory at f7e10000 (64-bit, non-prefetchable) [size=16K]
   Capabilities: <access denied>
   Kernel driver in use: oss_hdaudio
   Kernel modules: snd-hda-intel


HW mixing can be enabled/disabled in ossxmix (GUI) with a mouse click.
You can record the so-called "total mixed output" (playback + mic)
viewtopic.php?f=3&t=4656
http://en.wikipedia.org/wiki/Hardware_mixing

HW mixing is easy to detect:
1. Enable "vmix" in ossmix/ossxmix
2. Plug a microphone into your PC.
3. Speak into the microphone (but do not run any recording software).
4. Try different settings in ossxmix.

If you hear your voice in the speakers, it means that HW mixing is enabled.

You may try to patch it yourself.

Is this the Plan 9 community?

Well, I'll try to do something.

But I don't understand, why sound works ok, and muting is still selective and works ok too?

Because your codec is misidentified, and the generic "mixer driver" fails to detect "jacks" correctly,
see, for example, /usr/lib/oss/conf/oss_hdaudio.conf
Therefore, something works, and something does not.

To fix the problem, you have to patch the OSS4 code and recompile it. There are many examples on the forum.

Azalia based systems (laptops/motherboards) would require a custom driver to work properly
http://manuals.opensound.com/usersguide ... audio.html

Such custom drivers for HDA codecs/motherboards are not available for OSS4 and ALSA. On Windows, you are likely to have similar crap instead of "drivers".

Does the microphone works?
Have you already tried HW mixing or "surround playback"?

You may also try to find the developers. Although, of course, Easter holidays is a kind of "Ramadan".

> Does the microphone works?
No. Even

Code: Select all

ossrecord foo ; ossplay foo

doesn't work.

Playback works with and without vmix enabled.
