No audio on the recorded file

This may be a result of choosing the wrong record audio

If you are using an external audio patch cable, verify
that it is connected between the Audio-Out of TV tuner

AUX-In of your sound card and that you selected the
audio source to "AUX."
Check the ComproPVR in the Record tab of Settings
