Hi,
I use JRiver's latest version 31 after having had the previous versions for years.
I have a RME AIO card for audio and so far everything worked well, the card was recognized in wasapi.
Since the last versions of Jiriver, I have no more sound, I can always select my card in Wasapi but no sound.
Returning to version 31.0.43 I have the sound again ...
Regards,
Guy
