I think you should try to find the process that holds snd-aoa-codec-toonie reserved. Risto - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

I don't know. My older machines are forced to run an older kernel - 2.6.19-gentoo-r5 - due to the ATI driver dropping support for the chipset. Those machines work as MythTV frontend machines and on those machines (as on all my other machines) executing a restart of Alsa works. On this machine - my first MAc/PPC machine - it doesn't. This may well be a configuration issue caused by me. I just need to get to the answer. Looking at a simple x86-based mythfrontend, also running mythfronted, the modeules loaded are far simpler. myth14 ~ # lsmod Module Size Used by lirc_streamzap 13060 1 lirc_dev 10468 1 lirc_streamzap fglrx 390828 0 ati_agp 6796 1 agpgart24240 2 fglrx,ati_agp snd_atiixp 14604 0 snd_ac97_codec 89120 1 snd_atiixp snd_ac97_bus2048 1 snd_ac97_codec myth14 ~ # cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.13 (Tue Nov 28 14:07:24 2006 UTC). myth14 ~ # uname -a Linux myth14 2.6.19-gentoo-r5 #1 PREEMPT Tue May 29 14:58:25 PDT 2007 i686 Intel(R) Celeron(R) CPU 2.26GHz GenuineIntel GNU/Linux myth14 ~ # I looks like I must have built some of the support into the kernel, like USB support, and that machine doesn't have 1394. udev is loading a bunch of this stuff even though I don't really need it so I'll see if I can get that cleaned up. I don't require ipv6, 1394 (for now anyway). I'm not sure whether I need the drm module. Lots of things to figure out and improve. Still, it seems a problem that a simple restart fails.

Apparently 'Killing processes using ALSA' is not doing what it says. The topmost sound driver module, snd-aoa-codec-toonie, is used by 2 (processes). And kernel module unloader probably hangs.

The first list is before I start the rmmod and the second is during while the terminal is hung at 'Unloading Alsa modules'. No difference that I can see to apparently whatever is causing the problem stops anything from happening. This Mac Mini is running MythTV while I'm restarting Alsa. That isn't a problem on another MythTV frontend box that is X86 based as shown at the bottom of this email. Maybe I should take this to alsa-dev? I'm not sure if the developers read this list.

I got rid of snd_powermac and sound still works so the system is using snd-aoa as you suggested. However when I attempt to restart Alsa from the command line Alsa still hangs when it tries to unload the modules. login as: root [EMAIL PROTECTED]'s password: Last login: Fri Apr 18 12:35:42 2008 from 192.168.1.131 MacMini ~ # /etc/init.d/alsasound restart * Storing ALSA Mixer Levels ...
