Hello. I have just installed ProgDVB/ProgTV on a HP DV7 notebook with Win 7/32.

I've got the app working well on local OTA free to air DVBT including
EPG.

About 4 out of 29 channels have no sound audible. The channel info
Box shows similar info to other working channels. Video on all
Channels is fine.

Sound does work on other channels from the same provider.

Any ideas please, thanks Anton.

What type of audio not work? ac3?

ac3 I assume. Whatever is standard on a Win7 notebook.

Please install and select in ProgDVB ac3filter.
