No-Jun, could you take a look?

Comment 3

[No-Jun Park [:njpark]]

While I don't think it's a blocking issue (since it's not a regression either), i'm needinfoing hub to double check.

Comment 4

[No-Jun Park [:njpark]]

[Tracking Requested - why for this release]:
It does not reproduce on nexus 5l: making me suspect that this might be related to memory constraint. Tracking flag set since it's awaiting on ni? flag (Once the ni? is answered, we can decide to nom it for 2.5 or keep it in the backlog bin.

Comment 5

[Jim Porter (:squib)]

I feel like I fixed a similar issue recently, but I'm having a hard time finding it. Could QA take a look to see if this still happens?

I think this is actually an AudioChannel issue.

Not AudioChannel. I know what's going on here. Patch on the way.

Had a real hard time reproducing this problem, but it did happen. A JS error was being thrown from not having the <music-scan-progress> web component loaded during startup. I'm guessing this was causing a race condition where the song would not load if the error was thrown before we tried queueing up the song.
