Can you post output of 'ossmix' command?

[Maxa]

I have the same problem with the same sound card (M4A785TD-V EVO motherboard). Seems that as the outputs are programmable, mic and line-in are being used as stereo output

That's also what happens with osstest. pcm1 is speaker output+headphones, pcm2 outputs mic, pcm3 outputs to line-in jack in backpanel, pcm4 is headphones in front panel. Jack5 and 6 don't seem to affect anything.
Any way to force "correct"/wanted behaviour?

If I understand correctly, the problem is the recording doesn't work. Hmm.. You can try modifying record.select1.select1 in the mixer (with oss(x)mix), while testing recording on pcmin0 and pcmin1 using "ossrecord -d6 - | ossplay -" (-d7 for pcmin1) and testing for echo. You can edit /usr/lib/oss/conf/oss_hdaudio.conf and add the line "hdaudio_noskip=7", and after OSS restart ("sudo soundoff" and "sudo soundon"), you may have more controls in the mixer.

[Maxa]

I tried with the options in oss_hdaudio.conf, changed options in ossxmix while echoing with ossrecord+ossplay d6/d7... and still nothing gets ever echoed from any jack (except oscillation with mix ). Actually I'm more interested in playback than recording, I'd like to hear my preamplified guitar through computer (either line-in or mic); that setup isn't the problem as it works with other software and I can't hear my headset mike either.

I think what's described here is the root of the problem http://manuals.opensound.com/usersguide ... audio.html

The Intel HDA mixer is a new type of mixer that doesn't have the normal volume controls found on AC97 or legacy SB devices. The HDA mixer presents a concept of Jacks and you can configure any jack to be either an output or an input jack.
---
There is a function selector for most of the analog audio jacks (for example connector.pink.mode). This selector is used to control if the jack is used as an input (microphone or line in) or output (front, rear, side, speaker, etc).

However, there are no switches in oss(x)mix that could be used, and looks like by default all jacks are output (osstest).

One thing also comes to mind, chipset is AMD 785G/SB710, sound card is VIA VT1708S, so should it really be ATI HDAudio, not VIA HDAudio (kernel/drv/oss_hdaudio/.devices) or am i mixing oranges and apples?

[cesium]

No, it doesn't have to be ATI (some vendors mix-and-match hdaudio and board). Per the id, it looks to be VIA-based.
