Description of problem:
Sound is lost with 1075_FC4. It is fine with 1063_FC4.
This is due to the latest alsa patch in the -bk series. I know this
because I have been applying the bk-alsa patch to a vanilla
2.6.10 on my laptop and after the latest large patch the sound
stopped working there too. This big patch updates to alsa 1.0.7.
I don't know whether this is due to some incompatibility with the
alsa-lib and utils or internal to kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.update to 1075_FC4
This continues to be the case with 1.1076_FC4. I forgot to say that the kernel
2.6.10-1.1063_FC4 works fine and the sound driver is snd_intel8x0 and
PS: I just tried 1.737_FC3 and that has the same proble So, the sound stuff
in -ac8 is breaking something.
Still no sound with kernel-smp-2.6.10-1.1087_FC4!
The problem is that the card is not detected. True for 1.088_FC4 as well.
Consequently none of the sound devices created. All the modules are
loaded fine from modprobe.conf.
doing "cat /proc/asound/cards" tells you there are no cards found. With
a working kernel (1.1063_FC4) this produces:
0 [I82801BAICH2 ]: ICH - Intel 82801BA-ICH2
Intel 82801BA-ICH2 with AD1981A at 0xc800, irq 169
and a subdirectory card0.
still a problem with latest errata ?
does it redetect it if you run system-config-soundcard ?
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
