I recently downloaded the latest kernel as well as the latest bttv drivers (stable version 0.7.78) to my linux machine. I am using a WinTV PVR card from Hauppauge. While the compilation and installation went fine (even with kernel 2.4.9 version of bttv), I am facing an interesting problem. I get no audio when running the xawtv application. However, when I boot into Win2k and run the WinTV200 application and then immediately reboot into linux, everything works perfectly. I have gone through all the faqs and also numerous mailing lists. The only messages that I find relevant to my problem date back to 1998/1999. In that case, Erik Andersen has posted a patch to the file bttv.c. Obviously, the file is not even to be found in the current versions. I am reproducing the URL for your convenience (http://www.ultraviolet.org/mail-archives/linux-kernel.1999/0192.html). I am also providing the output (/var/log/messages) for the cards before booting into win2k and after. It is obvious that the MSP34xx chip is detected only after I have already initialized it in Win2k. Any insight you can offer will be highly appreciated as I have already spent a lot of time on this problem with no results. I am a relative newcomer to Linux.
