Hello, Since bttv 0.7.93, card with number 27 has changed : from MAXI TV Video PCI2 to Lifeview FlyVideo 98/ MAXI TV Video PCI2 LR50. With 0.7.92 all is working with sound. From version 0.7.93 to 0.7.100, I didn't have any sound. I think it's the same problem described by "Annoying hum" : http://www.wideopen.com/mailing-lists/video4linux-list/msg17542.html Thank you.
