I just added a C-Media C8738-MC6 audio card. For a long time the sound volume was very, very low and I had to run my speaker volume way up to hear it. Then I started playing with audio settings. I opened up K-Mix...for each slider there are green lights at the top and red lights at the bottom. I have no idea what they mean but when I clicked on the red light at the bottom of the PCM slider, suddenly the volume turned up to a normal, clear level. However, if I use the slider on RealPlayer, the volume goes back down...until I click the red light again. It doesn't seem to matter if I click it on or off, it just makes the sound normal. Questions: 1) What are these green and red lights? 2) Is there some way or some other setting I can change to make the normal sound volume 'stick' ?
Nobody's responded to this so I thought I'd repost. I am definitely not getting the performance I expect from my sound card. How do I know? Because my machine is dual boot with XP and in XP the sound is loud and clear. The sound in Linux, even with my tweak below is low and hissy ( like it's not putting out enough volume, so the background noise is emphasized ). This is really frustrating because this is the THIRD sound card I'm using. 1) The built in VIA chipset never worked with Suse. 2) I bought a SB Pro 24-bit live and they never wrote the full drivers because SB did not release the specs. 3) Now I bought a card that based on the Suse hardware database that was rated as being FULLY supported and there are still problems.

From reading the hardware matrix at www.alsa-project.org I get the impression that the 24bit is supported with the ca0106 driver module. Since I don't have this card I can't actually try it, but there don't seem to be any notes about difficulties in their list

Well, if RealPlayer screws up your mixer settings, that seems to be a bug in RealPlayer. I would suggest using another program for playing Real Media things until they get it solved. I think in kmix the button under the slide is the recording source. If you hover the mouse cursor over the light you should get a popup telling you what it is Could it be that you have a microphone connected to the system turned up really high? Because that could cause feedback and all sorts of audio problems. My cheap mic caused me no end of problems until I learned to mute it until I actually needed to record something.

1) Please don't top post - I doubt the quote attribution is correct, but I can't figure out who said what. 2) I had something odd happen on one of my systems here with an AC'97 sound on the MB (ASUS, but don't bother ranting at me - I like the P4B800s) that might give you a lead - I was hacking around with this machine as a dual boot, and at one point, I had a similar problem as you describe. Investigation showed that somehow the speaker and line in plugs had gotten reversed _IN SOFTWARE_. By that I mean that when running windows, the green plug was the speaker connection, and when booted to linux, it was the red plug... When connected wrong, if you crank the volume all the way up, you can get audio similar to your description out of the line in plug - just before you blow up the op amp chip... I don't know if that's your problem, but it's something to look into. Mike- -- Mornings: Evolution in action.
