3 months ago Yeah, I'm gonna need a little more details around the stereotool integration. This simple reproduction script works fine:
s = playlist("~/sources/test-stream/audio")
s =
stereotool(
library_file="/path/to/shared/lib",
s
)
output.ao(fallible=true, s)

3 months ago That's awesome. Let me get another pass at cleaning the base fix and we should be good to go.
Description
Stereotool (10.30) doesn't seem to work with Azuracast (branch
dev-ls2.3.x). Based on the error messages, it appears the issue is related to LS 2.3.0 rather than Azuracast.Azuracast discussion thread: https://github.com/AzuraCast/AzuraCast/discussions/7354
Steps to reproduce
Expected behavior
Steretool 10.30 to work with Liquidsoap 2.3.x RR
Liquidsoap version
Liquidsoap build config
Installation method
From official packages in the release artifacts
