Summary:                    aoss + skype: volume_adjust: SOUND_MIXER_WRITE_IGAIN
failed: Invalid argument
Description: 
I've tried 'skype' with my M-Audio Revolution 7.1.

Soon (probably in a second) after this command line:

aoss skype &

the terminal window gets filled with

volume_adjust: SOUND_MIXER_WRITE_IGAIN failed: Invalid argument

messages, and I do not hear anything in 'skype' connecting to their
automated 'echo123' service.

The message is not quite clear, and I believe it shouldn't flood the
screen.

I mean, the code should first check capabilities of the card and its
configuration and
issue the message once.


What is IGAIN in the message above ? Input gain ? That is, capture gain ?

Hmm, did you apply the patch for aoss above?
After applying the patch, try once aoss skype with softvol plugin in
~/.asoundrc and quit immediately.  This should create a user-defined
control "Capture Volume".  Then again aoss skype without ~/.asoundrc.

Takashi, three minutes after publishing the patch (06-08-05 14:50 ->
06-08-05 14:53) you said:

"
With revo 7.1, this might not work, too, since revo has really no "Capture
Volume" (corresponding to IGAIN in OSS).

If so, it must be a bug of Skype. Skype must check DEVMASK before reading
IGAIN. 
".

So, it was an indication for me that you were not insisting on the patch
anymore.

If you think the patch is worth trying, I'll have to allocate some time
for learning how to non-destructively compile ALSA.

Thanks,
  Sergei.
