The fix doesn't work...in fact it seems to have killed my Airtime :-(

Henry López del Pino

I'll check if things works.

That comment was intended primarily for the Airtime developers . If you
are not familiar with the GNU diff universal format for creating a patch,
you could have added extra characters that shouldn't be there and would
consequently prevent liquidsoap from starting.

The end result of the change to those lines of the ls_script.liq script
should look like this:

def create_source()
l = request.equeue(id="s#{!source_id}", length=0.5)

l = audio_to_stereo(id="queue_src", l)
l = cue_cut(l)
l = amplify(1., override="replay_gain", l)

After making the change, you then need to restart the airtime-liquidsoap
service:

sudo service airtime-liquidsoap restart

This will cause a brief outage to all your output streams and disconnect
any inputs so plan accordingly.

Hope this helps,
-Bill

Seems that this fix is working. My liquidsoap is working fine after edit ls_script.liq, but I didn't test yet with mono files (I replaced all files to stereo ones)

Possibly, although I moved the line in nano without adding anything extra...:-/ I don't use diff myself.

I've made the change to /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_script.liq and it seems OK this time, will try later with a mono file.

Confusing thing is I have 2 ls_script.liq's - the other is at /var/lib/airtime/tmp/python_apps/pypo/liquidsoap_scripts/ls_script.liq. A backup? I edited both last time...

Yes it works! Yay!

Hmm - I had an odd thing, and this was the only recent backend change I've done (not even apt-get update, cos it was up-to-date)?

Just found the stream was about 5-7 minutes behind what it should be, did a reboot and it's now 'in sync' with the schedule...could this change affect that?

Airtime-check all looks OK, before and after - I have silan taking up loads of CPU (again - I thought that was fixed in this version?) but apart from that looks OK and is streaming OK.

Howdy, Stranger!
