Asterisk 16.0.0 no alaw translation?

Asterisk Asterisk Support
1

HI there, was going to move from 13 LTR being the excited person i am i with the release of 16.0.0, but in my build yesterday i noticed that the alaw translation was missing now i know i selected the alaw option but i may have missed something but i recompiled a couple of times to make sure i wasn’t missing something to no avail.

The error i was seeing was

channel.c:5578 set_format: Unable to find a codec translation path: (gsm) → (alaw)

running the ‘core show translations’ showed it missing the alaw:

rest cut off to save posting space

For now I’ve rolled back to 13.23.1 (fresh compile no issues) to give version 16 some airing time in case it wasn’t just me and i can spend some more time on it later when i have more time but love is someone could confirm if it just me or this actually is happening with this release.

There hasn’t been anything done to the module for this. Are you loading it? (It’s codec_alaw.so). Are there any warnings on the screen? Are you selectively loading modules?

hmm strange, Nope was a fresh install only with same config files that previously worked and when i went back to 13 all was well again too.
No Manual loading , the codec shows as being loaded but there was no translation available when my phone tried to listen to some of the recordings that were gsm only.
Once i reverted it was able to translate correctly again.
All good just thought i’d mention in case it was something that was overlooked
Thanks for the reply

; **** you need to load the codec in /etc/asterisk/modules.conf ****
; Codecs
load = codec_alaw.so
