Hi again,

Following these instructions seems to fix it (at least in Subsonic). Is it possible to get this baked into DietPi, as well as upgrading to the new version of Subsonic:

Many thanks

@spectrumcomputing
Thanks for this info.

~~Ah I found the bug in our code. That was already found and fixed for Airsonic but with Subsonic it's the same. Will fix this, many thanks for reporting!~~

EDIT: Ah no this was indeed only an issue with Airsonic. So actually we do everything from your link exactly the same way. Not sure if just v6.1.5 was the solution in your case?

Subsonic now plays .m4a files perfectly. Thank you. Ampache still does not. This may help:

I enabled logging in Ampache by making some changes in the config file and this is the contents when I try and play .m4a files:

@spectrumcomputing
Thanks for the link. From there it seems quite clear how to enable:

G_CONFIG_INJECT 'transcode_m4a[[:blank:]]' 'transcode_m4a      = allowed' /var/www/ampache/config/ampache.cfg.php

But there are reported as well several issues with transcoding enabled on Ampache, which is why it is disabled by default: ampache/ampache#1048

You sir are a genius :-) Subsonic and Ampache now working perfectly. I will make a donation to the project over the weekend.

@spectrumcomputing
Thanks for reporting back.

I will add this as info to our online docs. As of above mentioned issues with transcoding on Ampache, we will not implement it by default, but instead direct users to the documentation about how to do so manually. Makes sense as well as you can enable much more sound formats that way.

EDIT: Ah no this was indeed only an issue with Airsonic. So actually we do everything from your link exactly the same way. Not sure if just v6.1.5 was the solution in your case?
