Description Benjamin Schindler 2005-08-30 14:33:59 UTC

Most recent kernel where this bug did not occur: 2.6.13 (git)   
Distribution: Gentoo   
Hardware Environment: athlon64 3000+ gentoo x86_64 512mb Ram   
Software Environment:    
Problem Description:   
I hava a hauppage video card that runs fine under linux. When I load bttv, I have to pass audiomux=1 in  
order to make sound work.  This worked up to 2.6.11. On 2.6.12 and later, I get video, but no sound 
 
dmesg output looks like this (upon loading modules):

Comment 1 Mauro Carvalho Chehab 2005-09-02 14:01:09 UTC

msp3400 has three different modes of working. There's an autodetection code
inside, based on revision number of the chip. Maybe it is using the wrong mode
on your card.

Please use two insmod options to msp3400 module:
debug=1 opmode=0

You should try also with opmode=1 and opmode=2.

Comment 2 Benjamin Schindler 2005-09-06 09:58:29 UTC

I'm trying right now 
 
With opmode=2, I get a lot of output, tons of:

I loaded the modules in that order: 
modprobe tuner 
modprobe msp3400 debug=1 opmode=2 
modprobe bttv (with and without audiomux=1)

Ok... sound works when I explicitelly load the msp3400 module - without any arguments at all. dmesg:

Despite this error, it works. However, before, I had to pass audiomux=1 to bttv for sound, but I didn't have 
to load the msp3400 module at all

Comment 4 Mauro Carvalho Chehab 2005-09-06 10:32:54 UTC

Try again without loading msp3400 and without audiomux=1.
bttv is capable of autoloading msp3400 module.

Mauro.

Comment 5 Benjamin Schindler 2005-09-06 11:00:31 UTC

Doesn't work here :-/  
 
When I don't load the msp module, I hear cracking sound when switching channels, but nothing otherwise. 
When I load the module (msp3400), I hear the cracking too (doesn't happen with 2.6.11 oddly), but sound 
is there too
