I have recently bought a Shuttle SN41G2 with an onboard i810 chipset. I'm running a SuSE 9.0, and replaced the default OSS driver with ALSA 1.0.1.
I redirected all my sound output through the SPDIF interface using /etc/asound.conf :
pcm.nforce-hw {
type hw
card 0
}
pcm.!default { type plug slave.pcm "nforce }
pcm.nforce {
type dmix
ipc_key 1234
slave {
pcm "hw:0,2"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
} ctl.nforce-hw {
type hw
card 0
}Yet the SPDIF output remains locked at 48 KHz, and so the sound is usually slightly altered :
abyss:/etc # more /proc/asound/nForce2/codec97#0/ac97#0-0 0-0/0: Realtek ALC650 rev 2
Capabilities : DAC resolution : 20-bit ADC resolution : 18-bit 3D enhancement : Realtek 3D Stereo Enhancement
Current setup Mic gain : +0dB [+0dB] POP path : pre 3D Sim. stereo : off 3D enhancement : off Loudness : off Mono output : MIX Mic select : Mic1 ADC/DAC loopback : off Extended ID : codec=0 rev=1 LDAC SDAC CDAC DSA=0 SPDIF DRA VRA Extended status : SPCV LDAC SDAC CDAC SPDIF=7/8 SPDIF VRA PCM front DAC : 48000Hz PCM Surr DAC : 48000Hz PCM LFE DAC : 48000Hz PCM ADC : 44100Hz SPDIF Control : Consumer PCM Category=0x2 Generation=1 Rate=48kHz SPDIF In Status : Not Locked
How can I control the SPDIF output through alsa?
Thanks,
Daniel
