Fedora 12 - Another strange audio problem
Just in case this helps someone else...I have a new installation of md-12, mostly works fine, except some videos have no sound. To fix it:
1. Open a terminal
2. su to root (don't know if this is needed)
3. Start alsamixer
[root@nick var]# alsamixer
4. Toggle the mute switch on each channel by pressing the "m" twice (i.e. mute then unmute, or, unmute then mute...whichever applies).
5. Now anything I play works...very strange.
Here's the thread I found it in:
BTW, it is toggling the mute button in the mixer that gets the audio pass through working. I agree that using the mixer should not do anything for digital sound, but it does.
