When asking the question I forgot pcp is mainly aimed at playting audio with squeezelite which may mean access to audio h/w is quite lax but you should check whether theuserid you are using to play arecord is either the owner of the alsa "file" or in the group "staff" If that is all OK - I still think you should methodically go through Alsa capture device by number - with both hw and plughw - to see if any work. The usual problems when testing audio capture with arecord : 1. Correct capture device 2. Permissions/groups 3. Line in level 4. problem on input cable or no audio on Line-in 5. check your output test actually works. The above are my check list - be careful on point 4 - it has caught me out a few times when convinced I had a complex problem. A sanity check on the captured audio files can be a hex/octal dump - after a WAV header, the audio samples of silence are all zero. Unless you have a hardware or driver problem - the audio capture should work and it is a simple process - so I'm guessing there may be finger trouble somewhere so double check and doubt yourself at each step. The USB id indicates a CM106 device and AFAICT for main Pi distributions (e.g. raspbian) there does not seem to be any driver issues although not many use "line-in" Line-in hardware can be independently tested on a Windows or other systems. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=109495 _______________________________________________ Squeezecenter mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/squeezecenter
