[ltp] Need help w/ sound on TP770 RH7.2

[Adam Benjamin]

You're in luck - I've had to deal with this problem quite a bit on my
TP 770E.  I don't know what the real cause of the problem is (and I'm
too lazy to really figure it out.)  Here's the poop:

When my laptop first reboots, something about the process leaves the
sound really unhappy.  However if I either:

a) suspend, then resume (includes hybernate)

b) unload, then reload the sound modules

then all is well.  I don't know why (as I said) but it works.  Here's
what I have in a script:

----------------------
#!/bin/sh

sudo rmmod cs4232
sudo modprobe cs4232
----------------------

You could make that a one-liner, but I left it that way out of
visibility (and sudo caches your success for becoming root.)  If you
don't understand the whole sudo thing, then just become root and
execute:

    rmmod cs4232
    modprobe cs4232

Like I said, you can also close the lid, wait for the suspend, and then
open it (assuming you have the bios set to suspend on close.)

I hope that helps,

Adam Benjamin
