Hi,

after switching from 2.6.34 to 2.6.36-rc5, the sound on my old Hauppauge analogue TV card has stopped working. Audio out from the TV card is connected to line-in of my motherboard (Gigabyte EG45M-DS2H) using the short cable that came with the TV card. Other audio sources (e.g. MP3 player) are audible when connected to line-in. The TV picture is fine.

The log messages look really similar for the two kernels.

2.6.34 works:

kernel: bttv0: PLL: 28636363 => 35468950 . ok

The only real change is that the IRQF_DISABLED warning is gone.

Cheers,
Richard

Hello,

my problem is still present in 2.6.36-rc7, the log output is unchanged from rc5.

All the best,
Richard

I can't remember of any functional changes at sound stuff that might cause such trouble.

The better would be if you could bisect what patch broke it and point it to us.

Thanks,
