Hi,
I've got a Hercules Fortissimo III 7.1 :
00:0a.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01) Subsystem: Hercules Fortissimo III 7.1 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (1000ns min, 6000ns max) Interrupt: pin A routed to IRQ 11 Region 0: Memory at e9100000 (32-bit, non-prefetchable) [size=4K] Region 1: Memory at e9000000 (32-bit, non-prefetchable) [size=1M] Capabilities: [40] Power Management version 2 Flags: PMEClk- DSI+ D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME-
I use it *only* via the optical output.
Now it seems the alsa driver that's in 2.5 with mute the optical output until black magic is performed in any alsa-compatible mixer.
Is there any boot option to tell alsa to activate the optical output automatically ?
The second question is, with the alsa tools present on freshrpms.net and optical output activated, the only mixer setting that seem to have an effect is the DAC.
Is there a way to set this knob as the default sound volume (as a kernel boot option ...) ?
Why is the dac controlling the volume even when I'm reading a CD (i.e. digital PCM input, digital optical output, what is the DAC doing here) ?
Sorry about the stupid questions, I found lots of material on building alsa (not really needed now it's in-kernel) but little on how to use it:(
