Description Of Issue
When I play a track, I get an error message that states ‘roon lost control of audio device’. If I press play again the track plays just fine. Sometimes it’ll keep on playing more tracks in the playlist, other times I have to press play again for each additional song.

Hi @Omid_Mostachfi,

Does this behavior only happen when playing certain types of tracks (one sample rate/DSD/MQA)?
Does the WASAPI driver experience the same issue?

No. Funny enough that’s a problem I have encountered and figured out. Before I changed the settings to ‘no mqa support’, Roon would skip mqa encoded songs (my motu DAC doesn’t have mqa capability) but still played other files types.
This is a different issue, Roon refuses to play and says it lost control of the device. If I push play a second time it’ll usually start playing (same file, no skip).
I just conducted a test to confirm, and it stalled on a tidal Flac file that was non MQA.

Hi @Omid_Mostachfi,

Thanks for the additional info. Can you please confirm:

Also, are you using the latest driver for this DAC?

I have the most recent driver and firmware for my DAC.
I ‘ll try WASAPI (I was hoping to avoid it, extra layer of window software).
I’ll report back.

I tried WASAPI. Roon skips every song regardless of the file type MQA or not (on the bright side, it doesn’t complain that it lost control of the device!).
I then switched to ASIO4ALL as the driver, and it seems to play fine, without skips or lost control problems!
Thanks.

Hi @Omid_Mostachfi,

Glad to hear the ASIO4ALL driver is working as expected in your setup!

For anyone using a MOTU DAC. I was having problems with Roon losing control of the device. I initially thought using the WASAPI driver solved the problem. It didn’t.
The issue occurred when Roon played a track at a different sample rate than the MOTU was set to. Once I set the motu to 96kHz, and had Roon convert all files to a sample rate of 96kHz, the problem went away.
