I'm using an Asus Transformer Book TH101.
While I'm on the login screen, I'm able to adjust the volume properly and can even hear the corresponding beeps. But after I login I'm no longer able to adjust the volume. As you can see in the screenshot below, the slider is completely grayed out.
I've tried reinstalling
pulseaudio, and when I run
pulseaudio --start I get
E: [pulseaudio] main.c: Daemon startup failed.
And when I run
alsamixer, I get
This sound device does not have any controls.
I'd really appreciate some help with fixing this problem.
