I cant find the setting to set the record device to PCM can you give me a amixer command line for it? Like I said aumix seems to be the only command line one I've found with that option/feature. Not that I've tried to do it other ways. $ aumix -q $ aumix -v R $ aumix -q The options for -p and -w seem to set it to mic for microphone input. In the gui mode it's the square with the green center square, click the one for master volume (first one) to set it to the pcm output as your default recording channel. It should turn/be red in the gui, when it is. There might be an amixer option for that. Alsamixer seems to only let me toggle mic capture ON, but NOT off, which undoes the change aumix made. I mainly use this feature to make a WAV of festival output for text to speech. Seems like aumix says Capture to on and Mic to off (relative to capture), when aumix changes things. With alsamixer I seem to only be able to set Mic to ON. Bear in mind that this is completely dependent on your hardware supporting this feature. Roughly %50 volume on my laptop. And it requires a soundcard that supports that. Otherwise use a cable to connection line out to line in. Which could be on that machine or another one. This is not a solution in my case, I don't have a line in jack connection. A somewhat related idea is how I can read audio from a file and pipe it to microphone input.

[Alsa-user] Redirecting the output audio to the microphone input
Hello. I like to redirect the sound I hear in the speakers to microphone, so it can be recorded with e.g. arecord. A somewhat related idea is how I can read audio from a file and pipe it to microphone input. I think alsa can do this with some sort of combination of plugin file, dsnoop and some asoundrc-fu but I cant get all the concepts to create a solution by myself. Someone can help me please?
