Hi

I recently upgraded from 3.2 to 3.7 and noticed, that I don't get any 
sound anymore from my TV-card. tvtime still works fine, just with no 
sound. As you can see from the snippet below, I have a hauppage WinTV 
card which uses msp3400 for sound

Here are the relevant snippets from the dmesg:

I'm also attaching my kernel config (self compiled using gentoo). As 
this is my first message, I don't know whether I have all the info you 
need. If not, just let me know
