Hello, I am using ivtv 0.2.0_rc3 under Gentoo (kernel 2.6.11-gentoo-r9). I seem to be having a problem playing back hardware-encoded mpeg streams through the hardware decoder on my PVR-350 (tuner type 47). The image shows up perfectly on the TV output. However, there is no sound. If I play the same stream to my computer screen, I hear audio as expected.
The streams are being recorded with mythtv, using the DVD setting, audio at 48000 sampling rate. When I play other mpeg files (i.e. not those created with the encoder), I *do* hear sound come through. I am fairly sure that those files were *not* encoded at 48000), so I thought that maybe the hardware decoder didn't like the 48000 sampling rate. However, I was not sure how to change that setting (if at all possible) with ivtvctl. I saw one setting, audio bitmask, which was part of the --set-codec-params option, but I could not find documentation on what that meant. Any help would be appreciated. --Alex P.S.
