| # We require pulseaudio.socket to be active before starting the daemon, because | |
| # while it is possible to use the service without the socket, it is not clear | |
| # why it would be desirable. | |
| # | |
| # A user installing pulseaudio and doing `systemctl --user start pulseaudio` | |
| # will not get the socket started, which might be confusing and problematic if | |
| # the server is to be restarted later on, as the client autospawn feature | |
| # might kick in. Also, a start of the socket unit will fail, adding to the | |
| # confusion. | |
| # | |
| # After=pulseaudio.socket is not needed, as it is already implicit in the | |
| # socket-service relationship, see systemd.socket(5). | |

Thanks so much for this. I was trying to setup squeezelite as a system service and having all kinds of problems getting audio working correctly. Tried your user service file and all working perfectly!
