Sound problem solved in OpenSuSE 10.3 (hooray!), but a question remains


After upgrading from OpenSuSE 10.2 to OpenSuSE 10.3, I had no sound. My sound card is a Via 8233, which uses the Via 82xx driver. I had noticed that the sound in 10.2 was a little faint, but I didn't bother to try to fix it.

I did the alsaconf quadrille, which produced a click but nothing else. Finally I tried configuring the card again in Yast, using the Edit option. I opened the Volume control (under Other) and saw four sliders at the bottom, all labelled VIA DXS. I set them all to the max and when I pressed the test button, the sound blasted out at me. Problem solved!

But the question remains: why are there four separate sliders and what is the difference among them? For that matter, what do they really do?

The existance or otherwise of a particular slider depends on the driver. As for what they do: take a look at the soundcard capabilities. Have you tried muting them one at a time to see what changes?

The DSX channels

The first DSX channel seems to set the volume and the others have no effect. Even though I've solved my problem, I'm wondering just what a DSX channel is. Is that particular to the Via 82XX cards or is it a more general term used with soundcards? Neither Google nor Wikipedia was much help on that.

By the way, I posted my query mainly in the hope that it would be useful to others. The questions I asked were out of curiosity, not necessity.

But why 4 sliders?

Thanks, Simon -- but do you know why there are 4 of them, of which only one produces an audible effect?

Well... the card provides 4 DSX channels, perhaps you are not using all the available features of your card?
You did read the documentation?
Is there a man page with the driver?

Found the info in the kernel sources

I didn't think there was any available documentation since the sound chip is on my motherboard and there's no pertinent man page, but I did find it after all. The source code for the driver explains everything. For those interested, it can be found at /usr/src/linux-2.6.22.9-0.4/sound/pci/via82xx.c.
