Hi everybody, I have a 4 input / 4 output USB audio card (Native Instruments Audio4DJ). This audio card does not provide a mixer device. I only intend to use one pair of speakers, so only 2 outputs are interesting for me (else I will use JACK). My ~/.asoundrc as it is now is here http://pastebin.com/8uG7R6A8 As you can see I have 2 stereo devices setup, Audio4DJ_A for channels 1/2 and Audio4DJ_B for channels 3/4. The combined device named Audio4DJ is for JACK use. I have added ctl.!default Audio4DJ_A pcm.!default Audio4DJ_A to the end to try to make it work with alsa apps by default. However, while the first app works correclty, the second I try to open complains about "cannot open, audio device in use". My understanding of ALSA is pretty slim but what I think I need to do is to create a mixer device for Audio4DJ_A (or equivalent) and make it default. I have a udev script which runs when I connect the Audio4DJ so that it puts the ~/.asoundrc in place when it connects and deletes it when it gets disconnected, so that I can use my onboard audio device when it is disconnected. The Audio4DJ USB card is device 1, while my onboard audio is device 0. I have this set up in /etc/modules.conf so that when I boot up my computer the USB takes does not become card 0 (which is bad because at some point I will unplug it and I will have no sound because only card 1 remains). Can anyone please help me tweak my ~/.asoundrc or give any advice whatsoever?
