Title:
[HP Pavilion dv7 Notebook PC, IDT 92HD81B1X5, Black Headphone Out,
Front] No sound at all
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
How do I disable auto-mute?
I'm a ubuntu noob.
Speakers work fine, but plugging in headphones = no audio. Take it out
and speakers work fine again.
Checked alsamixer, saw that the head phone jack was "muted" (MM) and 0.
If I make it (00), and up the volume, the headphones work.
Unplug headphones and plug back in, and it's muted once again (MM).
