alsa drivers and volume control


hey everyone,

I just installed the latest ALSA drivers and played some MP3s and CDs to test it out. They sound was fine, but I discovered that the only way I could adjust the volume was by using the 'wave' slider in alsamixer(or any other mixer). My soundcard is a SB Live! MP3+ w/ cambridgdge soundworks 2.1 digital speakers. Right now, I am using the digital out on the card. Any ideas on how I could change this so that the master and PCM sliders would work?

thanks,


peeks

Just a wild stab in the dark... I donīt really know what I am talking about, but if your using xmms try setting the output module to oss and then there is an option somewhere there to set the volume on xmms to change the actual volume.

Sorry I am so vague but I am at work with win98

Hope it helps anway

no luck

Thanks for the tip but unfortunately, it didn't seem to work Basically, my main problem is that the output volume can only be controlled by the 'wave' slider in a mixer. I would like to restore functionality to the master and PCM controls. It's not something that needs urgent attention but it's irritating to open up the mixer each time and fiddle with the wave level just to control the volume.

Hey did you look when you select oss output there is a setup for it and you can make xmms control the master volume (I think it is) When I get home I will have a look and tell you exactly where it is.

It sounds like you have exactly the same problem I had.

Yup thats exactly what I did before. If I remember right, you can find that option in the third tab of the OSS plugin configuration window. Oh and I should have mentioned this before.. this problem isn't limited to XMMS alone. I have to use the wave slider regardless of which app im using. The master and PCM controls don't work at all.

jim, that webpage had exactly what i was looking for.

"If you are using ALSA a few things are different. I'm using the DIN Digital out which means you cannot control the Master/PCM volumes as you would with analog out. These are controlled by Wave * mixer groups. This is actually better since you can control the volume for each speaker."

I think the only way I can use the master/PCM controls is if I use the analog output. I found one thing odd though:

"UPDATE:The developers have fixed the mixer controls in 1.0.0-rc2 so that PCM now controls PCM output for all channels. And Master controls all output volume. They also change AC97 to Analog Mix for my Audigy2."

Is the above info applicable if im using digital out?


thanks for the help dude,

pk

I am glad that helped... sorry I donīt really know much about digital outputs and that sort of thing. I have only had the most budget of sound (ie crappy built in) until recently when I bought a board that has 5.1 and digital output. Still havent got around to using the 5.1!!!

Good luck and I am sure that someone else on this forum will be able to help more, or maby look in google for sb how tos??

Adam
