Thanks, Laszlo Hello Laszlo, Please send correspondence to the linux-media mailing list, as the linux-dvb list is deprecated. Your firmware is fine. The extract_xc3027.pl script will *only* work if the md5 checksum matches, so if it matched then you ended up with the correct firmware. Regarding #1, the audio is working correctly. The problem is that for raw capture devices there is no way currently for the v4l2 to inform applications where to find the ALSA device that provides the audio. Your card is behaving consistently with *every* other product currently supported that provides a raw video stream (as opposed to products with an MPEG encoder onboard). The reason you see the audio being out of sync with the video is because of buffering of the audio prior to playback. You can usually control this behavior with command line arguments for arecord or sox.
