Description of Issue

I have a 24/192khz version of the album Temple of the Dog downloaded from HD Tracks. The album is stored on my Synology NAS as WAV, and Roon is reading this via a NFS share. Anyhow, Roon seems to think this WAV track is a MQA track as I see the following error in the log

08/13 05:55:54 Error: while reading for dCS Network Bridge: MQA decoder does 1x->2x but got sample rate 192000

– more of the log is below –

Hi @AHHYAYA ,

Thanks for the report here!

I’ve never seen a WAV file being read as MQA before, this is a strange one! Can you please upload the affected album to us so that we can test this further in the lab? You can send it to our diagnostics server below (please let us know once uploaded):

Thanks!

Hi @AHHYAYA,

Have you had a chance to upload the affected file? We’re standing by to investigate the issue at your convenience with our QA team.

Thanks for the reminder. I’ve been tied up with work. I have uploaded the affected file now.

In the mean time I’ve also noted other issues raised for this album…

Hi @connor - did you have an update on this issue? Still can’t get the track to play on the latest release of Roon.
