Recently upgraded my FE/BE systems to R5E50 from R5C7.
After many tweaks finally have a nicely working system except :

When I set up 5.1 surround sound every thing works but the channel mappings in alsamixer are weird :

Chip : RealTek ALC658

Speaker-test-------------------------------------Alsamixer channel
RR -------------------------------------------------- LFE
RL -------------------------------------------------Center
LFE,CTR------------------------------------------Surround
FL,FR------------------------------------------------PCM
FL,FR-----------------------------------------------Master

I guess I have two issues :

Most important. How can I get the volumes of All the channels to go up and down proportionately.

I've seen references to manufacturers "nice" controls for this but Logitech does not seem to have anything for my 5.1 speakers.

Less important is if there is a way to get the weird Alsamixer mappings straightened out.

Thanks.

After delving into the less than simple world of ALSA I found a solution to my number one issue : How to control all the 5.1 surround sound channels with one volume control. This link gives the background to the issue.

http://alsa.opensrc.org/How_to_use_softvol_to_control_the_master_volume

First I defined the following .asoundrc file logged in as user mythtv :



Then test the new control



go into alsamixer. A new control called SoftMaster should be there.
Test that when you use the new control the volumes on ALL channels change.

if the sounds are coming from the correct speakers at the correct time then :

I am using xine to play DVD's so the following relates to xine.

That's it. The remote now controls all the channels volumes when playing 5.1 surround sound.
