How do you enable the second analog output of Creative Labs SB Live! sound card in Gnome?

Asked by Jarno Suni on 2009-03-19

The sound card is "Creative Labs SB Live! EMU10k1 (rev 06)" according to lspci, "SBLive! Value [CT4832]" according to Gnome's Volume Control. In Xfce4 the track "Wave Surround" is used to control the second analog line out, but it does not have effect in Gnome session, no sound signal is output. I am using ubuntu 8.10. How do you control the second line out in Gnome?

In terminal, use

alsamixer -V all

command to show and adjust all channels.

It shows only two channels: Master and Capture, and they don't affect to the second line out.
(In an Xfce4 session much more tracks are shown, but Pulseaudio is not used there.)

I understand your problem, and I have the same sound card. I found a solution which is, removing all pulseaudio components. I always remove pulse after a fresh install, it just doesn't work well form me. Removing pulse and its components may remove ubuntu-desktop meta package, but it is not important. It doesn't affect your installed applications. Remove all pulseaudio packages and log out then log in. Try again. If you need, you can make an .asoundrc file in your user directory.

Thanks Ufuk, that solved my question.

Removing the package "pulseaudio" was enough here. There is a thread about Pulse audio removal at

This post does not recommend removing pulseaudio, though:
