[mythtv-users] Re: Alsasound not working

[Mike Schrag]

Unfortunately this problem doesn't appear to be something that can 
easily be fixed by just recompiling your Redhat kernel ... I have heard 
that you can recompile a stock 2.4.20 kernel and get it to work, but I 
don't know what issues that introduces into your RH9 installation.  
Incidentally I was able to do a one line change to one of the source 
files in alsa to get it to compile/load properly, but I can't vouch for 
whether or not it will cause terrible stability problems (which I have 
had some of, though it seems pretty good now).... Basically if you do a 
"grep schedule_work `find -type f`" on your alsa source, you'll see two 
references -- one that is the function call that is causing this error 
(in like snd.c perhaps?) and the other is a #define.  All I did was 
replace the function call in snd.c with the actual define value and 
recompile ....... it seems to work........ you're kind of on your own 
after that though.
