Hmmmm, this should not be an issue on vanilla raspbian systems.

Creating an actual home directory for a system like user to fix an edge case bug seems a little bit harsh to me.

glensc commented 4 years ago

shouldn't != is not. without fix users need deep Unix knowledge to fix the underlying problem.

this is not an edge case, it's a bug report from an actual Debian system

here's reproducer:

in any case, you must specify -m or -M to indicate if you want home dir to be created for new users:

if you want home dir to be created

I don't want a home dir to be created for the btspeaker user.

The reason I see this as an edge case is that the error only occurs if aplay delegates to pulse audio which I advise against using together with bt-speaker. (Added to readme)

Setting up pulses bluetooth plugins and make those work seem like a better choice.

Or using pulse as it is intended to be (at least in my understanding), as the actively logged in user. E.g., finding a way to avoid the btspeaker user to fix the problem.

System users (like btspeaker) usually do not have a proper home directory but a solution I could live with is explicitly setting it to /opt/bt-speaker so maybe we should do this with -d. 🤔
