Hey guys,
I am trying to decipher these audio dropouts. I just watched another bd rip dts-hd and two pretty good dropouts like 50% through the movie. the typical alsa underunn errors in the log, it is attached here
http://pastebin.ca/2103711
I am also attaching as many alsa outputs as I can think of to try and rectify this...all the below info is from the GT 430 I have installed.
sorry for the long post but I am ready to take a sledgehammer to this machine. I have tried a 210, 220, 430 and 520 gt cards and they all preducr some kind of audio dropout.
Thanks,
Dave
