I was able to get system sound working by adding my UID to the audio group. I still am not getting audio in Chrome however, but that might just be a bug in Chrome at the moment, as was suggested here. If anyone has any more Chrome specific suggestions, those would still be greatly appreciated.

I noticed the same problem once I got the most recent updates. I see you're also using alsa-mixer. If you're using it because PulseAudio was giving you problems, then my solution might work. It seems that PulseAudio got reinstalled (at least partially) with this round of updates. Once I removed Pulse, which you can do with this command: sudo apt-get ...

Problem solved... it was just a faulty usb port (actually usb 2.0 being dsiabled on bios) causing the trouble. Using a good usb 2.0 port the soundcard works off the bat, with just the asoundrc file. This card seems to not have any volume controls in alsa mixer just the channel maps which are fixed and cannot be modified.

The problem is Hydrogen (as Ardour) launch jackd at startup but don't close it at exit: But you can run killall jackd in a terminal after Hydrogen exit. A complicated way to use Jack and pulseaudio software at the same time is to install "pulseaudio-module-jack" (also install qjackctl (gui for jackd) and pavucontrol if not present). Restart ...

chose your speakers as the default output or if you use qpaeq use the one it adds as the source output or uninstall pulse and reinstall it this worked for me when my sound sources wouldn't show

There is a right and left balance control in the GUI interface for sound. Your question seems to indicate you prefer a terminal command, and so if that's the case I can't help you. However if you are merely determined to mute one of your speakers you should be able to configure that in your sound settings. Merely click once on the speaker icon at the top ...

Another option to what Babbzzz answered is to use GNOME ALSA Mixer. It's the exact same thing as the terminal program alsamixer but it is a GUI version. Simply run sudo apt-get install gnome-alsamixer in Terminal (or search for/install it in the Software Center/Synaptic.) Once installed you should be able to launch it from the HUD menu. It provides all the ...

PulseAudio controls underlying ALSA-level volume controls. Open a terminal. Enter alsamixer and press the Enter key. You will now see a user interface like below. Select your correct sound card using F6. Mute/Unmute with the “M” key. An “MM” means muted, and “OO” means unmuted. This was the problem I had once.
