Hello! I have WinTV TV card based on BT878A, correctly detected by driver. But there is no sound. I have just something like a single tone. How to fix it? For compare i have also Flyvideo 98 card based on BT878, detected as unknown - it works well. Here is it's lsmod : 00:0b.1 0480: 109e:0878 (rev 02) Subsystem: 1852:1852 Thanks Karol
