using more than one set of speakers and configuring them
I do not have surround sound speakers, but I do have a sound card with six sound jacks for surround sound on my motherboard. I have two normal sets of speakers. I got both sets of speakers working with sound coming out of both of them by enabling "duplicate front" in the gnome volume control, but there are a few problems. When I change the volume from the Volume Control in the gnome-panel , it only changes the volume for one set of speakers. How can I get it to change the volume for both sets of speakers? I just want for them to be at the same volume, and when I change the volume from the panel, it does not change the volume of both of them. The volume control in the gnome panel is controlling the master volume only, which is only controlling one set of speakers.
The same thing happens when using mute. It only controls one of set of speakers using one of those sliders that you see in "volume control" (right click sound icon and click open volume control) or alsamixer. There is another slider that controls the other set of speakers labeled as "Surround". It would be nice if master volume controlled all sets of my speakers. I would like to keep them synchronized so both sets of speakers have the same volume and both mute and unmute with one control instead of having to go into preferences everytime I want to mute both of them or change the volume. The master volume control in gnome-volume-control (the same slider that is controlled from the gnome panel volume applet), only changes the volume for one of the sets of speakers. gnome-volume-control shows my sound card as a NVidia CK804 (alsa mixer). lspci shows this. Code:

I don't know if this would work or not, but what if you disabled the "duplicate front" in Gnome and set ALSA to Suround 2.1 (4 speakers)?
You'd have to adjust the levels in ALSA so that your speakers were more evenly matched and you'd get no stereo seperation between the two that are "centre" and "sub" but it might be a better alternative to what you have at the moment. Cheers, Andrew. |
