Hello everybody,
I don't know if my question is right here, but either way I am asking:
I am using an old Benq notebook (Joybook S73) mit Xubuntu 15.04. When I installed a new kernel (then 3.19.0-16, but now I am using 3.19.0.28) the sound on the speakers stoped working and there were no more audible sounds. With headphones plugged in and a the highest possible volume I could hear very silent the music played on the PC.
Up to Kernel 3.2.0-70 the sound worked fine.
System update and upgrade unfortunately did not help. Do you have any idea what may be the problem?
I did the following to show the chip used:
simon@simon-Joybook-S73:~$ lspci -nnk | grep -i audio -A2
00:1b.0 Audio device [0403]: Intel Corporation NM10/ICH7 Family High Definition Audio Controller [8086:27d8] (rev 02)
Subsystem: Benq Corporation Device [17ff:0600]
Kernel driver in use: snd_hda_intel
simon@simon-Joybook-S73:~$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0x6c400000 irq 29
Thank you for your help!
Simon
