Glad I saw this, this exact problem has been driving me crazy for a while. Sometimes the sounds works, sometimes it does not. I noticed that the bug report has been closed - NOTABUG. a configuration problem. I'm sorry, but when the sound does not work on an out-of-the-box install, something is just plain broken. So the solution is for everyone to examine all their modules to determine the correct loading sequence, and then blacklist certain modules? I can't believe they left it at that. Can someone here voice an opinion: is this an ALSA issue or fedora issue? Why does it just happen to certain select people (I assume it is a rare problem). thanks, brian On Thu, 2007-11-29 at 22:16 +0100, Wolfgang Paul Rauchholz wrote: > Problems seems to be fixed by adding the following line t > o/etc/modprobe.d/blacklist: > blacklist snd-intel8x0m > > https://bugzilla.redhat.com/show_bug.cgi?id=389521 > > Thanks for your efforts Bill and Nigel. > > > > On Nov 28, 2007 8:56 AM, Wolfgang Paul Rauchholz > <wp.rauchholz@xxxxxxxxx> wrote: > I booted the laptop and there is no sound. > As mentioned before, the sound/no-sound situation occurs at > random to me.
