Hey, I've made some progress on the issue. Turns out the instructions in the Wiki or the Makefiles are wrong. The name of the "card" is loopback and not aloop as stated in the Wiki. My problem is now that I can't load the module. The syslog says something about "disagrees about version of symbol struct_module". Any ideas what could be wrong and more importantly how to fix it? Thanks, James [snip] ./configure --with-cards=loopback --with-sequencer=yes make make install root@domU-12-31-38-00-2E-13:~# ls -la /lib/modules/2.6.16-xenU/kernel/sound/drivers/ total 24 drwxr-xr-x 2 root root 4096 2008-07-29 19:35 . drwxr-xr-x 4 root root 4096 2008-07-29 17:14 .. -rw-r--r-- 1 root root 13356 2008-07-29 19:35 snd-aloop.ko root@domU-12-31-38-00-2E-13:~# modprobe snd-aloop FATAL: Module snd_aloop not found. root@domU-12-31-38-00-2E-13:~# insmod /lib/modules/2.6.16-xenU/kernel/sound/drivers/snd-aloop.ko insmod: error inserting '/lib/modules/2.6.16-xenU/kernel/sound/drivers/snd-aloop.ko': -1 Invalid module format root@domU-12-31-38-00-2E-13:~# tail -f /var/log/syslog Jul 29 19:39:21 (none) kernel: snd_aloop: disagrees about version of symbol struct_module [/snip] ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
