Sound Blaster Live! 5.1: only rear speakers

[papaschtroumpf]

This problems has been plaguing me forever.

 

I have tried to fix it multiple times, but I can't figure it out. Spent another 2 hours playing with KMix and alsamixer but to no avail:

 

I have a Live! 5.1 running under 2005LE snd-emuk101 driver.

I only get sound when I plug the speakers in the black jack, which is supposed to be the rear speakers. The green jack doesn't produce any sound.

 

I only use a 2.1 speaker set, and the subwoofer simply filters uses a filter to pick up the bass, so I really used only 1 jack. This means I can sort of live wiht the situation, but it means thatthe "Wave Surround" slide in KMix is what controls my volume, the "Master" slider has no effect.

This means that the KMix applet slider has no effect either.

 

Strangely enough the volume slider in Amarok or Kaffeine do work to control the volume.

 

 

The main issue is, why don't I have any sound to the front speakers?

 

I have tried going into alsamixer and turn all the sliders to 75% (and enabled the corresponding output toggle). Played with the "switches" tab, then did this all over in alsamixer. No luck.

Can you post the output of: amixer scontrols

Play with the settings of digital output. I have a sblive5.1 on Mdv05le and it works great - but I remember I had to mess with that a bit. Read my config page for 05le and 06...

aRTee I'll check out your page, I wouldn't find a page that explained how to enable/disable digital audio when I was playing with this yesterday. I didn't think about looking yours up.

Don't use 'wave surround' but 'surround' . (and try enabling '3d control')

 

If you don't see a 'surround' channel in alsamixer try with the amixer command: amixer set Surround unmute (and mute if you want to mute :) )

 

And look at what jacks are used by the microphone and other line ins. On some boards jacks can be used for both in and out. Make sure the switch is set to out when you connect a speaker :)

 

Tip: just typing amixer shows you all channel settings
