Hi,
This one was easier than getting the on-board LAN to work.
Judging from the Asus online product specifications the same audio hardware
seems to be present also on the non-Deluxe version; the other unknown PCI
device id in audio class seems not to work with the AC97 drivers so I assume
that it is the much-touted APU.
With this patch the on-board AC97 audio controller and Realtek Semiconductor
ALC650 CODEC work as far as I can test; tested with headphones in line-out
and playing two albums of MP3 audio with mpg123.
dmesg extracts, boot -v:
pcm0: <Nvidia nForce2 AC97 controller> port 0xd400-0xd47f,0xd000-0xd0ff mem 0xc9080000-0xc9080fff irq 11 at device 6.0 on pci0
pcm0: ac97 codec id 0x414c4720 (Realtek Semiconductor ALC650)
pcm0: ac97 codec features 20 bit DAC, 18 bit ADC, 5 bit master volume, Realtek 3D Stereo Enhancement
pcm0: ac97 primary codec extended features variable rate PCM, double rate PCM, reserved 1, center DAC, surround DAC, LFE DAC, reserved 4
pcm0: sndbuf_setmap 7b5000, 4000; 0xe0b97000 -> 7b5000
pcm0: sndbuf_setmap 7b9000, 4000; 0xe0b9b000 -> 7b9000
...
pcm0: measured ac97 link rate at 47999 Hz, will use 48000 Hz
The only noticeable error I heard while playing the MP3s was a slight
but audible pop after mpg123 starts playing; this might be something in
the mixer control code. Anyway, it's just cosmetic, didn't bother me
with headphones at normal playing volume.
Regards,
MSH
