Failed to listen by your 2nd patch.(I couldn't succeed by patch -p2 < YourPatch again. So I modified by hand, again.) And soon later, I'll test the Daniel Koukola's change(What you call "your original change"). Picked from /var/log/messages

The log doesn't matter in this case... Did it work (i.e. the sound is heard)?

ok. I didn't know the log doesn't matter. As I've said "Failed to listen", the sound isn't heard.
