Perhaps one of the developers can help out. Here a short summary of the problem: (details, logs, etc. can be found in my previous messages: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg10537.html http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg10562.html ) * Alsa rc1 * ASrock Mainboard K7S8XE with SiS748/963L + CMI9739 onboard sound * modules loaded without problems (snd-intel8x0, snd-ac97-codec, ...) * soundcard is correctly(?) detected: alsamixer shows: SiS SI7012, C-Media Electronics CMI9739 * mixer is working fine (I can control e.g. the volume of CD analog input) * PCM playback blocks: applications seem to wait for interrupt from soundcard. When running e.g. aplay, proc/asound/card0/pcm0p/sub0/state shows state: RUNNING trigger_time: 1070397701.434501000 tstamp : 1070397750.192659000 delay : 7194 avail : 4806 avail_max : 0 ----- hw_ptr : 4804 appl_ptr : 11998 and hw_ptr doesn't change over time. I have no sound daemon running. Before starting aplay the sub0/state was 'closed'. * same behaviour with oss-layer, alsa, alsa mmap. xmms hangs when I hit the play button. * No PCM sound is output * /proc/interrupts shows no IRQs sent from soundcard: ... 2: 0 XT-PIC cascade 5: 0 XT-PIC usb-ohci, ehci_hcd, SiS SI7012 8: 1 XT-PIC rtc ... Is there anything else I could try? Any additional debugging information I can provide besides the info in the 2 user-list mails mentioned above?
