I am using ivtv cards, and of the 4, 2 PVR-250's have a good volume 
level by default, the 1 PVR-150 is a LOT lower than the others, and I 
have an Avermedia M179 that is louder than the others. I don't think the 
audio level can be changed on the M179, but the 150 can, so I've been 
using a patch posted to one of the lists to disable the Myth audio 
adjustment, and manually turn up the 150 so it's about the same as the 
250's. Having a way of setting the level per card would be a very nice 
feature, and I realize that the coding involved is probably not trivial, 
but having the column in the db at least would allow someone who is 
motivated to work on it without having to futher change the db schema. 
Making it take up to 65535 would probably be easiest, but for the user 
making it a percent would be easier...

Just a thought.
