Hi Lyonel and Romain.
Two points.
1) I do have an updated set of instructions. I should clean these up a
little and post them to the list. The commands are each on a single line.
Just to make it easier to know what is happening. They can easily just be
copies into a shell script and run.
While it is possible to give Liquidsoap SUDO privileges. I always try to
limit security exposure unless necessary. The installation does not happen
very often anyway.
I have not tried your daemon install script Romain. I had my systemclt
service done before you wrote that..
2) Regarding Pulseaudio and Liquidsoap on a Raspberry Pi. I have not tried
input from Pulse, but I am not sure that the Pi is fast enough for it
output (at least the older B+ model that I tried it on).
I have not looked at any code, but externally, it looks like Pulse sends
the request for the next buffer before Liquidsoap is ready for it. And
Liquidsoap loses that request. So both programs sit and wait for the other.
Unfortunately, Pulse is the ONLY way to get Bluetooth audio with the latest
release of BLUEZ. :(
