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.

And I believe that the card should have, and it's possible to do, input gain control - please see https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1187 . Aslo, I'm repeating what I've said in the issue above: " *** I still have no capture with my Revolution 7.1 (issue 0001096) *** . Since I'm not getting it work, I've been trying to use ALSA utilities ('amixer', 'alsamixer', 'aoss') - "trial and error" approach - to make it work, and have found other problems on the way. Resolution of these other problem, including introduction of gain control, will not solve my main problem - lack of capture. I would appreciate getting an answer to the question in https://bugtrack.alsa-project.org/alsa-bug/view.php [^]?id=1096 : " Maybe my previous question does not contain enough details. Here is the rephrased question: Running 'amixer' with this command line amixer cget numid= , where
