Kodi 18 AAC stereo audio not working on DVB-T.

[ashley]

hi @Oberon, I tried the latest Kodi 18 nightly (and previous Kodi 18 builds).
One problem I see immediately is that 2.0 audio AAC does not come through.
If I use the latest test build of SPMC this works fine.
SPMC identifies the DVBT- feed with no audio on Kodi 18 nightly as; "2.0 AAC 1.85:1 H.264" whereas Kodi 18 just identifies the feed as "H.264".

There are no audio issues with DVB-T feeds identified as "5.1 DOLBY H.264".

Please can you investigate where the problem lies and take it to the Kodi forums if appropriate?
thanks.

Dvblink does not alter the stream. So Kodi forums is best place to ask.

thanks, is the problem you are mentioning relating to this;
https://forum.dvblogic.com/viewtopic.ph ... e7#p118500

The Kodi ticket has been opened here;
https://forum.kodi.tv/showthread.php?tid=328817
so @Oberon, it would be great if you can comment in the Kodi forums to get some traction on this.

Honestly, I do not think it is related in any way to the PVR API changes. It is more the issue of Kodi built-in player.

thanks @Oberon, I have updated the Kodi ticket with the log files (one with no audio), the other that appears to work correctly.
Would be great if you could take a quick look over on the kodi post referenced above.

I guess that the past of the Kodi log file that shows what is happening is;

by the way, I'm happy to work with you to fix any other kodi related issues (whether they are Kodi or dvblink issues) if that helps.
cheers
