No sound after resume

mattd7591 · 06-24-2007, 08:28 PM

I am using suspend2ram and suspend2disk to try and save energy on my computer. However on resume, sound doesn't work.
I tried doing /etc/init.d/alsa-utils restart as others said that works, but it isn't working
Im using Debian Lenny with a Soundblaster Live audio card

Perhaps you can try to unload the sound modules after stopping sound. (modprobe -r MODULE)
You might install "hibernate-script" to do all this for you automatically (see suspend2.net). In addition you might want to try suspend2 (which is very fast and has many features).

someone suggested that on Debian forums with a script like

Code:

while [ "`lsmod | grep ^snd" != "" ]
do
MODULES=`lsmod | grep ^snd | awk '{print $1}' | sed -e ':a;$!N;s/\n/ /;ta'`
modprobe -r ${MODULES}
done

modprobe emu10k1x

However doing

Code:

while [ "`lsmod | grep ^snd" != "" ]
do
MODULES=`lsmod | grep ^snd | awk '{print $1}' | sed -e ':a;$!N;s/\n/ /;ta'`
modprobe -r ${MODULES}
done

results in

Code:

matt-debian:Desktop# ./Text\ File
./Text File: line 5: unexpected EOF while looking for matching ``'
./Text File: line 8: syntax error: unexpected end of file
matt-debian:Desktop#

1st, are those "Code:" blocks the same? Please tell me where the differences are? If they are the same, & they look it to me, why did you post both? Putting both in your post implies they are different & need to be looked at separately. Looking for non-existent differences is a waste of my time.

As for your problem, I believe you're missing a '`' in your "while" statement -- just like the error msg says.

Yeah, they are the same. I don't know why I posted it twice.
I also figured out why it wasn't working.
I didn't write the script and am unfamiliar with awk and sed.

The only issue now is that I have to close sound apps to unload the modules, but that is only really an issue when listening to long files (such as tapes)
