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 ? ====================================================================== ---------------------------------------------------------------------- tiwai - 06-13-05 14:30 ---------------------------------------------------------------------- No, such a software conversion shouldn't be in the kernel code. It's a job of user-space. That is, such a feature could be implemented easily on alsa-lib, but this can't be used through kernel OSS emulation. The fix of alsamixer should be already fixed in 1.0.9b. Please update your system. I know there is a bug in amixer (the bug report isn't closed), but currently this is still in the deep of my long TODO list. If anyone can take a look and debug it, it'd be appreciated. BTW, you can do the following instead of amixer, if you don't like the interactive program: - alsactl -f somefile store - edit somefile manuall - alsactl -f somefile restore ---------------------------------------------------------------------- sst4 - 06-13-05 16:05 ---------------------------------------------------------------------- Takashi, regatrding " you can do the following instead of amixer, if you don't like the interactive program: - alsactl -f somefile store - edit somefile manuall - alsactl -f somefile restore " - please find attached 'asound.state.generated_by_alsaconf' file generated by 'alsaconf'. Before generation I cleaned up /etc/modprobe.conf by removing all sound related entries from it. Could you please tell me which lines to change and how in the 'asound.state.generated_by_alsaconf' in order to enable capture ? Please note that the word "capture" does not appear in the file. Regarding 'amixer'. The bug that I filed affects only control number 0 - maybe 'amixer' is still good enough to enable capture ? Anyway, please let me know how to enable capture either through changes in the 'asound.state.generated_by_alsaconf' file or using 'amixer'. Thanks, Sergei.
