Title:
[Inspiron 1470, Realtek ALC272, Speaker, Internal] No sound at all
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
I can get perfect sound through headphones, and the kernel recognizes
the internal speaker, but nothing is ever played through it. I have
personally tested a pair of earbuds to make sure that sound could play
through the headphone port, and that isn't a problem. The sound driver
just refuses to recognize the existence of the speaker, even though
the kernel does.
I wouldn't be surprised if the last upstream update had something to
do with it.
