Hello all, I have been using the bttv and bttv2 driver with xawtv and the test series of 2.4 kernels for some time now. I have had a problem for a while now, but didn't notice its symptoms until recently. The problem exists in every version of bttv and bttv2 + Linux 2.4-testx I have tried. The latest I have tried is bttv 0.7.42, bttv2 261000 and linux 2.4-test10. I have a WinTV PCI PAL - BG/I 61324 Rev 208 containing a BT878KHF and Micronas MSP3415B3. When I try to grab video from my WinTV device, the following error message is logged: Aug 1 21:04:14 dragon kernel: msp34xx: I/O error #1 (write 0x12/0x0a) Aug 1 21:04:15 dragon kernel: msp34xx: I/O error #2 (write 0x12/0x0a) Aug 1 21:04:15 dragon kernel: msp34xx: I/O error #3 (write 0x12/0x0a) Aug 1 21:04:15 dragon kernel: msp34xx: giving up, reseting chip. Sound will go +off, sorry folks :-| A more detailed log may be found at the bottom of this message. The effects of this when capturing from the composite input seem to be nil, I still hear sound despite the error message. However, I recently started to use the coaxial input on my card. When I grab from the television* input, I get the error message and no sound. My assumption is that the msp34xx card is not employed when using the composite input as sound and video is already demultiplexed. Recent bttvs + Linux 2.2 do not have this problem. Is this a known bug? I have been unable to find any documentation on this problem. I am using an Athlon processor, FIC SD11 motherboard, es1370 based sound card, (have tried stock and ALSA drivers) and Haupauge WinTV PCI capture card. Most of the related kernel code is compiled as modules. I have no penguin on my i2c bus that I know of. Thanks for any input! == ...
