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 ? ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- duplicate of 0001096 no capture with M-Audio Revolution 7.1 ====================================================================== ---------------------------------------------------------------------- tiwai - 06-15-05 15:44 ---------------------------------------------------------------------- I don't understand what you mean "enable capture" in general. One of your bugreports told that you could capture (even on OSS) with a certain application. Again, revo has no capture control. At least, the hardware spec I got tells so. The thing that Skype aborts when no IGAIN exists is the bug of Skype. It has to be fixed by the application itself. Please report this to Skype at first. As a workaround of this problem, you can add a softvol plugin to create a virtual volume attenuator. For example, pcm.revocap { type softvol slave.pcm { type hw card 0 } control { name "Capture Volume" card 0 } } Then, define "dsp0" PCM: pcm.dsp0 { type asym playback.pcm "plughw:0" capture.pcm { type plug slave.pcm "revocap" } } so that aoss uses the newly defined capture PCM. ---------------------------------------------------------------------- sst4 - 06-28-05 00:59 ---------------------------------------------------------------------- Takashi, please unmark the issue as duplicate of duplicate of 0001096. The latter was regarding capture (loopback) functionality as a whole, and this one is regarding certain error message in OSS emulation mode. Issues can be marked as duplicate if resolving one of them automatically resolves the other and vice versa. It is not the case. Thanks, Sergei.
