Update: possibly due to the file size.

Later I found out that Strawberry is able to play smaller DSF files, the largest being 350MB. The files in question in the original post are each about 1GB. Could file size be the cause of the problem?

Thanks for the wonderful music player, I have been a happy user since
discovering Strawberry in the Software Center of Solus.

However, I ran into the problem of not being able to play DSD audio earlier
today. I have Strawberry 0.6.10 and gstreamer-1.0 1.16.2 on my machine. I
loaded some large DSD files (about 4 GB per album split into 4 files) into
Strawberry using CUE files, and it was able to recognize them. When I tried
to double-click the tracks to play, Strawberry consumes around 50% CPU (while
memory usage remained usual), and wasn't able to play, skipping to the next track
after less than 30 seconds.

The following terminal message is from running ~strawberry --verbose~ and trying
to play one of the DSD tracks before it switches to another track:

I am able to play those DSF/DSDIFF files with MPV. Is there something I can do
to be able to play them with Strawberry?

Your help will be greatly appreciated. Cheers!
