Hi All, I'm trying to get my M-Audio Quattro to work as a second device in addition to my SoundBlaster Live! I'm using ALSA 0.9.6 and have managed to get them both to work. I am using Patrick Shirkey's asound.conf, however i can only seem to use the quattro as devices quattro1 and quattro2. Jack fails with any other settings that are defined in asound.conf. I've compiled Patrick's qinit program but it segfaults. My asound.conf is: # quattro1 is pcm0 which has a maximum sample rate of 44100 and 16 bit stereo pcm.quattro1 { type hw card 0 device 0 } ctl.quattro1 { type hw card 0 } # quattro2 is pcm1 which has a maximum sample rate of 96000 and 24 bit stereo pcm.quattro2 { type hw card 0 device 1 } ctl.quattro2 { type hw card 0 } # quattro2 is pcm2 which has a maximum sample rate of 96000 and 24 bit stereo pcm.quattro3 { type hw card 0 device 2 } ctl.quattro3 { type hw card 0 } #---- # # compose 4 channels from two channel x two devices, hw:2,1 and hw:2,2 # assuming that hw:2,1 and hw:2,2 give the same condition, 24_3LE/96k # pcm.quattro { type multi; slaves.a.pcm "hw:0,1"; slaves.a.channels 2; slaves.b.pcm "hw:0,2"; slaves.b.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave b; bindings.2.channel 0; bindings.3.slave b; bindings.3.channel 1; } ctl.quattro { type hw; card 0; } # # remap 4 channels as interleaved. # use plug instead of route here, since 24_3LE is unlikely supported by # applications. # # arecord -r 44100 -c 4 -f s16_le -D q4 -d 5 /home/xxx/q4.wav pcm.q4 { type plug; slave.pcm "quattro"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.q4 { type hw; card 0; } # # Use route plugin for applications that do support 24_3LE # This lowers latency which the plug plugin introduces due to resampling. # # arecord -r 44100 -c 4 -f s16_le -D q41 -d 5 /home/xxx/q41.wav pcm.q41 { type route; slave.pcm "quattro"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.q41 { type hw; card 0; } #---- pcm.emu10k1 { type hw card 1 } ctl.emu10k1 { type hw card 1 } and my modules.conf is: # START alias char-major-116 snd alias char-major-14 soundcore # Quattro alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # SBLive alias sound-slot-1 snd-card-1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss alias snd-card-0 snd-usb-audio options enable=1 alias snd-card-1 snd-emu10k1 options snd-emu10k1 extin=0x3fc3 extout=0x1fff enable_ir=1 Is there anything I am obviously doing wrong. Any help would be appreciated. Cheers, Adam
