Audio channels missing.

I'm not sure if i'm using the correct jargon for this, but I have been using fedora for a while now after switching from ubuntu.

My laptop has several sets of speakers. The main speakers (2 of them), the "subwoofer" (1) and the headphones for output. Windows agrees, ubuntu agreed. I can set the volume on any of those chanels / devices whatever in windows or ubuntu.

In fedora, I can ONLY set the volume for the main speakers on the front. If I tell the system to mute, it will still have volume coming out of the "subwoofer" at a fairly high percentage of full blast (about 75 - 80% if that's important) and the headphones as well.

In alsamixer, there is only one column.

You can still mute and change the volume if you go into the actual program generating the sound, like totem and change the volume there, but it's still a major thorn in my side.

Does anybody know how to fix this?

I have alsa-utils and all that jazz. I just need to find a way to get fedora to recognize my outputs.

And see if there any useful un-checked options.

Thank you. You gave me a lead. Apparently, alsamixer was opening the wrong "card" even though to the best of my limited knowledge, I only have one card.

Apparently I just have to open alsamixer and state explicitly which card to use. PITA, but at least it works now.

Thanks again!
