Sigmatel STAC9708/011

Sigmatel STAC9708/011

[fmoraes74]

On ALSA 1.0.4, there was a control called Sigmatel on the mixer for the emu10k1x STAC9708/011 mixer.

Now, on ALSA 1.0.5a, the control is gone even though I could use it to control the volume of one of the hardware buffers.

Any reason for the removal? If the removal is needed, should I add it back?

Hmm?  It's still there.

In pci/ac97/ac97_codec.c:

static const ac97_codec_id_t snd_ac97_codec_ids[] = {
...
{ 0x83847608, 0xffffffff, "STAC9708/11",	patch_sigmatel_stac9708,	NULL },

Well, for some reason I don't see the control anymore on gnome-alsamixer or alsa-mixer. It used to be the last one displayed and it is not there anymore.

How can I debug this? I will take a look at the ac97 document but I was pretty sure about this.

Also, do you have any idea of why I am hearing noise/cracks when I record at 8Khz instead of 48Khz?

Check the contents of /etc/asound.state after running alsactl store,
and see what's shown in the files /proc/asound/card0/codec97#0/*
files.

If it's a cracking noise, it's often the mismatch of the buffer/period
size between software and hardware, or the mismatch of the sampling
rate (hardware think it's 48k but software process in another rate).

What's exactly the symptom on your hardware?
Please show the information as I wrote in my previous mail...

Again: PLEASE show the information as i wrote in my previous mail,
/etc/asound.state and /proc/asound/card0/codec97#0/* files.

Here's the stuff you asked for. I unmuted all channels and maximized the sliders. Only register 0:04 is still muted as I explained before.

Also, I've split the channels into separate PCM devices for now, because I wanted to test sending output to a specific device. Is that ok? It is the same as done with the Audigy LS.
 
I am trying to clean up the code a little bit and I've also added capture support and fixed a few bugs I found.

I guess the attached patch fixes the problem.
Could you give a try?
