I have a computer running Ubuntu 20.04.2 LTS. I have a USB DAC (Musician Pegasus) plugged into one of the USB ports. I have JRiver MC 27 installed with various music file formats in the library (FLAC, ALAC, DSD). It was working where when I played a file I would hear music.
Something has changed and now it does not work. Although, the DAC switches indication to display which sample rate is is receiving correctly, but I hear no sound. If I play a DSD file I do hear sound.
I have connected this DAC to a Windows machine via USB running JRiver MC and it works fine, so the DAC is good.
I have the audio device in JRiver MC set to " hw: CARD=Audio,DEV0 [ALSA] USB HiRes Audio, USB Audio, Direct hardware device without any conversions "
None of the boxes in "DSP Studio" are checked.
Previously it was working when I had the default sound options in Ubuntu set to " HDMI / DisplayPort 2 - Raven/Raven2/Fenghuang HDMI/DP Audio Controller ", but this does not work anymore, in fact when I run the audio test in Ubuntu's settings the sound always plays through my USB DAC no matter which setting I choose. It is as if the operating system has taken over the USB DAC and will not allow JRiver to use it.
I have attached photos of the settings that I hope help.
Thank You,
