** Summary changed:
- [jaunty regression] no sound with hp laptop and HDA intel
+ [jaunty regression] No sound with HDA intel after 2.6.28-5 (worked up through
2.6.28-4)
** Description changed:
Sound used to work with 8.04 and 8.10 (usually after unmuting a channel), but
I can't get jaunty alpha 3 to play any sound.
The hardware is a hp hdx9480 laptop with a Intel HDA chipset. (tIntel [HDA
Intel], device 0: STAC92xx Analog [STAC92xx Analog])
- I checked all channels with alsamixer and alsamixer -D hw:0 and I can't find
any muted channel.
+
+ [Also confirmed on Thinkpad T61p with Intel HDA. Rebooting with
+ 2.6.28-4 or earlier restores sound. 2.6.28-5 and 2.6.28-6 are broken.]
+
+ I checked all channels with alsamixer and alsamixer -D hw:0 and I can't
+ find any muted channel.
Other information:
s...@hape:~$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xec004000 irq 23
I tried to check whether sound works with aplay
/usr/share/sounds/alsa/Noise.wav. It reports no errors and the volume
bar in pavucontrol shows that music is playing.
