Hi, I have just browsed through last 8 months of this mailing list archive and from what I read I guess that the PCTV Pro (year old one, with supported MT20xx) is not working in stereo (neither TV nor FM radio) yet. As I have just found a reliable way how to detect if the output sound is actually stereo or not I am wondering if I can help debugging the issue. I am running kernel 2.4.22 with its bttv 0.7.107. Xawtv does not offer any sound mode selection (mono/stereo/lang1/lang2). Syslog contains messages like "setstereo stereo" until I start xawtv - then it switches to "mono setstereo". The same problem was discussed here several times in last months so there's nothing new to say, apart from my offer to apply any patches and to test if the stereo sound appears or not. Petr
