I booted the laptop and there is no sound.
As mentioned before, the sound/no-sound situation occurs at random to me. I
cannot recognize any pattern.
The reason I have not taken out PulseAudio yet is that I suffered the same
problem under FC6/FC7 for which I moved to Ubuntu 7.x where sound ran
stablel. Therefor my hypothesis is that there is probably an issue with FC
and not PulseAudio??
I went to sound card detection and played the test sound with known result;
no sound. The screen shows the following info:
Vendor: Intel Corporation
Model: 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)
Module: snd-intel8x0
...
PCM device: Intel 82801DB-ICH4
1. alsamixer
Card: PulseAudio
Chip: PulseAudio
View: [Playback] Capture All
Item: Master
There is one bar in the center of the screen. From the bottom to top the
values are:
<Master>, 65<>65, 00
The channel is not muted.
