Description of problem: Pulseaudio totaly fails if the card is sb16 via ISA bus (=needs manualy loading snd-sb16). After update form F7 the card was detected and used, but pavucontrol sigsegv. After some fidling around the alsa configurations ware rewritten and now even alsa does not see the card. It's however still possible to load sucessfully the modules. Version-Release number of selected component (if applicable): ------- rpm -q alsa-lib -------- alsa-lib-1.0.15-1.fc8 ------- rpm -q alsa-utils -------- alsa-utils-1.0.15-1.fc8
The problem seems to come from hal. Because lshal does not lists all appropriate components: lshal | grep alsa udi = '/org/freedesktop/Hal/devices/computer_alsa_timer' alsa.device_file = '/dev/snd/timer' (string) alsa.type = 'timer' (string) info.capabilities = {'alsa', 'access_control'} (string list) info.category = 'alsa' (string) info.udi = '/org/freedesktop/Hal/devices/computer_alsa_timer' (string) udi = '/org/freedesktop/Hal/devices/computer_alsa_sequencer' alsa.device_file = '/dev/snd/seq' (string) alsa.type = 'sequencer' (string) info.capabilities = {'alsa', 'access_control'} (string list) info.category = 'alsa' (string) info.udi = '/org/freedesktop/Hal/devices/computer_alsa_sequencer' (string) For that reason it also does not change the device permissions and users do not have access to them. This was revealed when I removed alsa-plugins-pulseaudio. However the pavucontrol still sigsegvs, so there is still some problem with pulseaudio too.
pavucontrol has a bug which causes it to segfault when no sound card has been identified. See http://pulseaudio.org/ticket/172 This will be fixed shortly upstream. You say the device is properly identified by the kernel but HAL doesn't find it? This is most likely an issue in the kernel driver, and probably similar to the issue described in #370821. I am reassigning this issue to HAL now. David will probably be able to tell you quickly if this issue is the same as #370821. Please paste the outputs of "tree" here, similar to those posted in that bug report. I will ping the guys on the ALSA ML about this, too.
