Thanks. I tried that, didn't work, but it did cause me to wonder if there was something about the track (that I wasn't previously familiar with) that might be causing the problem. I put the output settings back to the wrapper sink, tried to play another track, and...it worked. The track that had me convinced something was wrong just had a significant period of silence at the beginning for some reason.
Complete pilot error. Mea maxima culpa.
Strawberry 1.0.22, MacOS 13.6.4 (Ventura).
I've been using Strawberry with all my music mounted via an SMB share for months now. It was working on Tuesday. I left it sitting, paused, on Tuesday night. On Wednesday I was away from home all day. Thursday morning, I came back to my computer and hit play and....no music. I can see the track timer incrementing at the bottom of the window. I get sound for notifications and other things.
As far as I can tell, there haven't been any changes to the system (no OS updates, for instance) in the last couple of days.
Have tried
Any suggestions for troubleshooting/fixing this?
@jonas - I'm in for $38. Can you post your paypal address here and I'll send it that way?
I coincidentally just signed up at $5/month support then ran across this thread. I'm a MacOS user and really appreciate being able to avoid iTunes. 
How are you doing on the donations for the system?
I'm trying to put together a smart playlist that will skip anything with a 1, 2, or 3-star rating (yes, that's weird). I built one with three conditions: rating not equal <1 star>, rating not equal <2 stars>, rating not equal 
stars> with AND to match all conditions.
It keeps adding songs with 3-star ratings to the playlist.
I'm willing to believe there's something odd for ratings in the database, particularly since when I looked at it with a SQLite editor it says that the "ratings" field is INTEGER but the values are...not integers, but also not exactly .2, .4 and so on. I expected them to be 0-5, or at least 0, .2, .4 exactly.
Any advice? If there are values the ratings "should be" to make this work I have no problem editing the database.
