I have audio crackling issues in video clips in Arena 7.23 and 7.23.1. Even in Alley when I trascode to DXV audio get worse than other codecs, just sound nearly intelligible. I have my Arena installed on a Asus Vivobook with rtx4060 mobile. Someone have this same issue? I have a presentation tomorrow and this drive me crazy. Thx

Try changing the audio devcie to the windows - exclusive mode one if you see it.
Or do a computer restart.
I suspect the Windows update I got recently messed up something with the audio driver, I sometimes get audio muted too, with the devcie looking like it's not muted, but muting and unmuting it in the windows audio controls gets it unmuted properly.

Thx Zoltán.
I found the problem!
It was the audio codec. When I trascoded works well. Avoid this codec.
