[mythbuntu] Mythbuntu 8.10 w/ Hauppauge WinTV Go - Ubuntu Forums

  • First I changed the Capture Card settings in the Mythbuntu back end settings to capture audio from my sound card: /dev/dsp (instead of the tv card - /dev/dsp1).

    Then I patched TV card line out to sound card mic in.

    I then used gnome-alsamixer (had to apt-get install it) to inspect the sound card settings.

    I muted the Mic and checked Rec

    A suspicious setting at the far right 'Capture' I also checked Rec

    After doing this I got synched audio for live TV and recordings.

MythTV/Install/Feisty/Troubleshooting - Community Ubuntu Documentation

  • This happens with the following combination: Ubuntu 6.10, mythtv 0.20, software encoding tuner card, VIA 8237 chipset. The default sample rate is 32 kHz. However the VIA 8237 chipset only do well with 48 kHz.

    To solve the problem, open mythfrondend, go to Utilities/Setup -> Setup -> TV Settings -> Recording Profiles -> Software Encoders -> Live TV and change the audio sample rate to 48 kHz. Test effect. Then do the same to settings in Default, High Quality, Low Quality.

    This solution is based on the MythTV Wiki.
