Hello, I have a Avermedia card AverTV Studio with VCR and radio. My problem is that the video I see good but the sound nothing. My messages file it's the following: May 13 03:33:00 zapater kernel: i2c-core.o: adapter unregistered: bt848 #0 May 13 03:33:03 zapater kernel: bttv: driver version 0.7.65 loaded May 13 03:33:03 zapater kernel: bttv: using 2 buffers with 2080k (4160k total) for capture May 13 03:33:03 zapater kernel: bttv: Bt8xx card found (0).
