[linux-audio-user] Advanced Linux Sound(ALSA), PPC, M-audio Duo

I am trying to user USB-AUDIO product with a TI laptop for a portable digital recorder. I have followed the instructions at http://www.alsa-project.org/alsa-doc/doc-php/template.php3 ?company=Midiman&card=USB+Audio+Duo&chip=Cypress+AN2131XX&module=usb-audio The compiles for building alsa-driver-0.9.0rc6, alsa-lib-0.9.0rc6, and alsa-utils-0.9.0rc6 went smoothly. The utility snddevices ran with no errors. When running the commad alsamixer, I get the error message "No mixer elems found." Proc/asound appear to have the correct entries dr-xr-xr-x 4 root root 0 Dec 7 16:55 card0 -r--r--r-- 1 root root 0 Dec 7 16:55 cards dr-xr-xr-x 2 root root 0 Dec 7 16:55 dev -r--r--r-- 1 root root 0 Dec 7 16:55 devices lrwxrwxrwx 1 root root 0 Dec 7 16:55 MidimanDuo -> card0 dr-xr-xr-x 2 root root 0 Dec 7 16:55 oss -r--r--r-- 1 root root 0 Dec 7 16:55 pcm dr-xr-xr-x 2 root root 0 Dec 7 16:55 seq -r--r--r-- 1 root root 0 Dec 7 16:55 timers -r--r--r-- 1 root root 0 Dec 7 16:55 version With Proc/asound/card0 having -r--r--r-- 1 root root 0 Dec 7 17:00 id -rw-r--r-- 1 root root 0 Dec 7 17:00 oss_mixer dr-xr-xr-x 3 root root 0 Dec 7 17:00 pcm0c dr-xr-xr-x 3 root root 0 Dec 7 17:00 pcm0p -rw-r--r-- 1 root root 0 Dec 7 17:00 stream0 I found the contributed utility qinit and it runs correctly with the hw name = "hw:0,0". With the "dmasound_pmac" module, dd if=/dev/dsp of=/tmp/sound.out bs=1024 count=1 would produce a file filled with unsigned bytes. The rest of the day was spent trashing about in config files to no effect. Questions: Should alsamixer work with the M-Audio Duo? After enabling with qinit should dd dump data? Any help, or fellow travellers would be appreciated. John Phillips
