Hi! I am using ALSA 1.0.13. My default sound card is CA0106. I thought that dmix was supposed to be enabled by default for all devices: From http://alsa.opensrc.org/index.php/Dmix : >NOTE: For ALSA 1.0.9rc2 and higher you don't need to setup dmix. Dmix is enabled as default for soundcards which don't support hw mixing. However when I try to play two files simultaneously on the surround51 device I get: $ aplay -D plug:surround51 test.wav & aplay -D plug:surround51 test.wav [1] 15892 Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: main:550: audio open error: Device or resource busy $ [1]+ Done aplay -D plug:surround51 test.wav $ Whereas the following succeeds: $ aplay test.wav & aplay test.wav [1] 15916 Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono [1]+ Done aplay test.wav $ I believe my /etc/asound.conf and ~/.asoundrc files are currently in their default states.
