I've tried using a usb soundcard on the same machine, and everything works fine there, so I think this is only the snd-cs46xx driver. I'm not sure what other info is useful - please let me know. Thank you. ====================================================================== ---------------------------------------------------------------------- jaime - 05-04-06 12:11 ---------------------------------------------------------------------- Takashi. I've got it working by "toggling capture" (enabling recording) for the ADC channel (in addition to making sure that recording is enabled on both the Mic channel and the "Capture" channel). Seeing how alsaconf sets up the volume sliders and unmutes certain channels so that users can immediately get sound out of their machines, would it also be a good idea to make alsaconf set capture enabled on the ADC channel (and perhaps set the levels up a little) so that users can also immediately use software that needs audio capture? (I do realize that this can all be done using amixer or alsamixer, but I think one of the points of alsaconf is to set levels and so make users' lives a little easier). I've also got another qustion: with arecord -v -v -Dhw:0,0 -f cd test.wav I get a volume meter which works and the wave file is good. But when I use: arecord -v -v -f cd test.wav I just get: Recording WAVE... Plug PCM: Rate conversion PCM (48000, sformat=S16_LE) Its setup is... Slave: Direct Snoop PCM Its setup is... Hardware PCM Card 0 'Sound Fusion CS46xx' device 0 subdevice 0 Its setup is... and then everything stops. There's no volume meter (like previously) and the wav file is only 44 bytes long. Would you prefer me to put this new problem into a new bug report? Thank you. ---------------------------------------------------------------------- atler - 05-08-06 12:14 ---------------------------------------------------------------------- It also seems to be the case in this bugreport: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1822 Recording with 'arecord -v -v -Dhw:0,0 -f cd test.wav' works fine.
