No Sound on Gigabyte z77-DS3H mobo's integrated audio

[HelloLion]

I recently built a new computer and (as of yesterday) successfully have Windows 7 and LMDE dual booted and everything appears to be working well except that when I'm booted into Linux my computer produces no sound. My sound is using the built in sound in my Gigabyte z77-DS3H mobo and works fine in Windows.

I've plugged my headphones into the front and rear ports and there's no sound. Pulse Audio shows sound if I play sound but I hear nothing. I've tried every setting I could see in the sound options and have also tried to use Gnome-Alsamixer (it won't open) and I've used the alsamixergui from terminal (doesn't seem to work right either). I've also looked around online for possible solutions and have produced no results with anything I've found so far.

This sound issue is currently the only thing stopping me from using LMDE as my main OS and Windows only as necessary so help would be very much appreciated. I'll be glad to try anything and to produce screenshots and other information.

Thanks in advance.

Not sure if I'm missing something? I don't see an "Auto-Mute Mode". Might just be a newb.

Can't you use ALSA Mixer as device? Then there should be an Options tab.
Don't know much about OSS - last stable release 2005?!?

It gets more mystifying at this point.

GNOME-Alsamixer won't open (as stated in first post). I reinstalled it and still it won't open. So I tried opening up Alsamixergui via terminal and I see this:

Since I didn't see any options that looked helpful I went to select sound card but when I try to select it it crashes and I get this:

I have no idea what is going on.


EDIT: I may have somewhat misunderstood what you asked, but in volume control my options under "device" are:
Intel PantherPoint HDMI (OSS Mixer)
Playback: Internal Audio Analog Stereo (PulseAudio Mixer)
Capture: Monitor of Internal audio Analog Stereo (PulseAudio Mixer)
Capture: Internal Audio Analog Stereo (PulseAudio Mixer)

none of which are the Alsamixer

Sorry, I'm not always clear. That's what I meant. But I also have my device with (ALSA Mixer) as an option. Now I don't know if you can just install ALSA or if it breaks anything. For me it was installed from the beginning (201109 ISO). The last updates came with UP4 from debian.linuxmint.com/latest:

Code: Select all

2012-04-05 19:44:57 upgrade alsa-utils 1.0.24.2-1 1.0.25-1
2012-04-05 19:45:26 upgrade gstreamer0.10-alsa 0.10.35-1 0.10.36-1

Sorry for being a total newb but I'm not exactly sure what I'm supposed to do at this point? Linux is still a new experience for me.

In terminal this will give you the installed and candidate version of the tools:

Code: Select all

apt-cache policy alsa-utils gstreamer0.10-alsa

I just bought this board. I am still trying to figure it out, it may not be pertinent but it may help to know that those ports in the back are apparently configured with some software provided by Gigabyte.

Found my own answer. Posting for others.

amixer -c0 set "Channel Mode" "6ch"
alsactl store
restart pulseaudio server

Long story short:

Code: Select all

echo "options snd_hda_intel model=generic" >> /etc/modprobe.d/alsa-base.conf
reboot
