Sound won't work on laptop after reinstall, previously worked fine.


I just reinstalled Debian 7.4 amd64 on my HP Pavilion dv7 Notebook PC and my sound won't work. It worked previously with no configuration on the previous install (which was also Debian 7.4 amd64 and running the exact same programs as the reinstall except for wine). Here are some outputs:

Here's the output of "alsamixer":

What's strange is that on my laptop's idiot lights, the audio indicator is orange (it's normally white) indicating that audio is unavailable or muted. Pressing the indicator does not do anything (and I don't now if it should, I never use those built in multimedia buttons).

I have gotten no error outputs while working within the OS relating to audio, and all the programs (e.g., banshee, vlc, mplayer, YouTube Adobe Flash) work as if there was working sound.

In both Windows 7 amd64 and Knoppix 7.2 IA-32 the sound works fine without configuration so the sound card is functional hardware-wise.

I'm not exactly sure what you mean, the LXDE Volume Control applet indicates I'm not muted, and pressing the orange-audio-idiot-light does nothing.

run alsamixer

press the right arrow to get to it (or to each unmuted control)

press the m key to unmute, pressing again will re-mute

then once you have happy with other volumes do this

Code:
sudo alsactl store
reboot to test settings are now saved

good luck

Thanks! Everything is working fine now!

I wonder why it was on mute by default...

I may know the answer from one distro

sidux was a debian sid which has transformed into aptosid and a forked siduction
sidux forum said they muted because they thought a number of people would install Linux at a library and so on reboot would have excessive sound
