Hi, I've been using 8.1-RELEASE on this desktop machine for a few months already, but only now found the time to look at a couple of problems with snd_hda and suspend/resume it still has. Maybe someone here has hints to fix them - I'd be grateful to hear them.
Audio with snd_hda(4) works, but only if loaded as a module AND only if I load the module AFTER booting. If I compile it into the kernel or add snd_hda_load="YES" to /boot/loader.conf, dmesg shows the following: hdac0: HDA Codec #0: ATI RS690/780 HDMI pcm0: <HDA ATI RS690/780 HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac0 hdac1: HDA Codec #0: Realtek ALC885 pcm1: <HDA Realtek ALC885 PCM #0 Analog> at cad 0 nid 1 on hdac1 pcm2: <HDA Realtek ALC885 PCM #1 Analog> at cad 0 nid 1 on hdac1 pcm3: <HDA Realtek ALC885 PCM #2 Digital> at cad 0 nid 1 on hdac1 mixer(8) shows: Mixer vol is currently set to 75:75 Mixer pcm is currently set to 75:75 There is no audio in that case. Unloading and reloading the module (or just loading the module manually after the boot process) logs: hdac0: <ATI SB600 High Definition Audio Controller> mem 0xfe024000-0xfe027fff irq 16 at device 20.2 on pci0 hdac0: HDA Driver Revision: 20100226_0142 hdac0: [ITHREAD] hdac0: HDA Codec #0: Realtek ALC885 hdac1: <ATI (Unknown) High Definition Audio Controller> mem 0xfdffc000-0xfdffffff irq 19 at device 5.1 on pci1 hdac1: HDA Driver Revision: 20100226_0142 hdac1: [ITHREAD] hdac1: HDA Codec #0: ATI RS690/780 HDMI pcm0: <HDA Realtek ALC885 PCM #0 Analog> at cad 0 nid 1 on hdac0 pcm1: <HDA Realtek ALC885 PCM #1 Analog> at cad 0 nid 1 on hdac0 pcm2: <HDA Realtek ALC885 PCM #2 Digital> at cad 0 nid 1 on hdac0 pcm3: <HDA ATI RS690/780 HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac1 mixer then shows: Mixer vol is currently set to 75:75 Mixer pcm is currently set to 75:75 Mixer speaker is currently set to 75:75 Mixer line is currently set to 75:75 Mixer mic is currently set to 0:0 Mixer mix is currently set to 0:0 Mixer rec is currently set to 75:75 Mixer igain is currently set to 0:0 Audio then seems to work fine. (Plugging earphones into the computer's case's front plugs doesn't do anything, though - audio still comes from the speakers attached to the plug at the back of the case. Any ideas about that?) Loading snd_hda from a startup script would probably work, but I guess that's not the way it was meant to work. The other problem is with suspend/resume: Suspend To RAM (S3) works by using "acpiconf -s 3", and pushing the power button wakes the system up again. Everything seems to work, only the LCD monitor remains off. (There also seem to be occasional cases in which the keyboard doesn't work any more, but I haven't really looked at that, yet. Usually, the system comes back up properly.) Loading dpms(4) doesn't seem to make a difference. The only way to turn the display on again seems to be typing "shutdown -r now" blindly. Regards, Stefan
