Hi,
I am having the same problem as user user4711 no audio. It was working in previous versions x64, though unsure which one 7.31 ?
I have connected my laptop via HDMI to my TV and there is sound. I too have tried changing all setting in sound options and codecs
Windows 10 x64
Log files attached,
Thanks Mark

#19Sorry. Logs not working in last release of ProgDVB
Fixed in prerelease https://www.progdvb.com/download_progdv ... lease.html

Re: Audio Not Working in ProgTV DVB
#20About audio. Looks like not good codec for AC3. Try install and select in ProgDVB settings - AC3filter (https://ac3filter.net)
Re: Audio Not Working in ProgTV DVB
#21Have loaded ac3filter to replace Lav filter - still no sound. Have attached new logs - will send password to you by direct email - thanks

Re: Audio Not Working in ProgTV DVB
#22Hm. No errors in logs. Check audio levels in File->Direct show-> Audio decoder.
ps: Also you can try change audio renderer to system and demux (of first page of options) to Microsoft. But in looks like current configuration is good.

Re: Audio Not Working in ProgTV DVB
#23I have tried what you have suggested on audio decoder AC3Filter properties opens and there is movement in input levels for AAC and AC3- but still no sound. I then changed audio renderer type to system that made no difference. Just to check it is not my system, I then uninstalled your current version and reinstalled version 7.30.04 all working. I think this is the last version without audio problem though I cannot be 100% sure. I am happy to work with you to solve the problem please advise - thanks Mark
Re: Audio Not Working in ProgTV DVB
#24I can now confirm that the last version working with audio was 7.31.0. All audio formats AAC MPEG and AC3 then stopped working.
Re: Audio Not Working in ProgTV DVB
#25No one report with same problem. You must have some specific settings of ProgDVB or windows.
Please try install ProgDVB to different folder (for example c:\ProgDVB) with portable mode for total reset on settings. Same problem? Is it depended from demux?

Re: Audio Not Working in ProgTV DVB
#26I have done what you have suggested. I loaded a portable version of the latest 7.32.1 x64 in C:ProgDVB drive no sound trying Lav and AC3 filter
I then loaded a portable version in a different folder in C: of version 7.31 all sound working.
When I first had this problem I did a fresh install of Windows on my desktop but it made no difference. I usually customise the Win 10 image I use on my desktop and was thinking I had created the problem myself.
The last few hours I have loaded a fresh install of Windows 10 1909 x64 image without any modification on to my laptop.
I repeated the above with the same result – so perhaps others have not been complaining about the problem.
I hope we can work to solve this issue as I really enjoy your program.
What does “Is it depended from demux” mean? Thanks Mark

Re: Audio Not Working in ProgTV DVB
#27Not need reinstall windows. This is request to much time and not help in 99% of cases.
Demux on first page ProgDVB settings. Also you can try Audio renderer in ProgDVB.

Re: Audio Not Working in ProgTV DVB
#29Same Problem here.
1 machine windows 7 64, other W8.1 64bit
Installing AC3 codecs or disable audio processor did not work.
Now reinstalled v. 7.31, now sound is working
