Responsible Changed From-To: freebsd-i386->freebsd-acpi Over to ACPI maintainers. State Changed From-To: open->feedback It's likely that the driver doesn't support suspend/resume well. The power tree merge may have helped with this (i.e. BAR restoration) so please try 5.3. The load/unload failure is the driver's responsibility. State Changed From-To: feedback->closed Feedback timeout |
I own an ASUS 8400K laptop, the sound card is : 00:06.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12) Subsystem: Asustek Computer, Inc.: Unknown device 1049 Flags: bus master, medium devsel, latency 32, IRQ 10 I/O ports at f800 Capabilities: [c0] Power Management version 2 I load the snd_maestro3.ko module at boot time via /boot/loader.conf The sound card works well but when I wake-up my laptop after a suspend mode (zzz) it often don't works anymore. I've tried to put some lines in the rc.resume to fix the problem : rc.resume: /usr/local/bin/sudo /sbin/kldload snd_maestro3 rc.suspend: /usr/local/bin/sudo /sbin/kldunload snd_maestro3 /usr/local/bin/sudo /sbin/kldunload snd_pcm But sometimes it can't unload the module (it says it's busy) even If NO application is using it (even in runlevel 1). Here is the dmesg output concerning the sound card, I see some error, maybe it can come from this: wakeup from sleeping state (slept 99:02:22) pcm0: <ESS Technology Allegro-1> port 0xf800-0xf8ff irq 10 at device 6.0 on pci0 pcm0: failed to enable memory mapping! pcm0: <ESS Technology ES1988 AC97 Codec> If I don't unload the module before sleeping I get this kind of error: pcm0: m3_rdcd timed out. pcm0: Codec reset retry pcm0: m3_rdcd timed out. pcm0: Codec reset retry pcm0: m3_rdcd timed out. pcm0: Codec reset retry pcm0: m3_rdcd timed out. pcm0: Codec reset failed pcm0: ac97 codec init failed wakeup from sleeping state (slept 00:00:18) pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. pcm0: m3_wrcd timed out. Every application works as it should be but no sound is played. How-To-Repeat: load the sound module, work with many applications, close everything, try to unload the module... If I don't unload the module before zzz'ing I get less or more the same problem too, I can use a mixer etc... everything works as if the soundcard worked but no sound can be heard.
