Description of Issue

Roon has recently started issuing the error message “ Roon lost control of the audio device ” on 24bit flac files (not all) but only with the Chord WASAPI driver, the ASIO driver works normally. Files up to 88.2khz are unpredictable & sometimes fail after around 5 seconds but anything above that rate fails immediately.
This affects streamed files (Qobuz) and locally stored files.
I have removed & reinstalled the Chord drivers & transferred the data files onto an internal hard disc but this hasn’t resolved the problem.
My broadband connection has been tested by the local engineer, sessions proved stable and speeds consistent at 42/15.
Any ideas to resolve this frustration would be welcome.
Thanks in advance.

No idea if this is relevant

Audio stops, but track is still playing

Hello @Matthew_Cole, Are you using the Chord ASIO driver or the Windows 10 WASAPI driver? The Chord Mojo has previous known issues with the Windows 10 WASAPI driver, I would try using the Chord ASIO driver instead. You can find a link to the driver here https://chordelectronics.co.uk/product/mojo/ You may also be able to resolve this issue by disabling “Event Driven Mode” in the “Show Advanced” menu of “Device Setup” for the Chord Mojo zone. -John

Hi Ged, thanks for the response. I have just checked out the thread, I enabled “Use Event Driven Mode” and it’s looking very promising, one troublesome track played for the first time in a week. I’ll run some more intensive checks when SWMBO has “retired” and I have some P&Q.
Thanks for the lead, I’ll report back.

ps. more interestingly, roon is now reporting the correct signal path information as well.
