Wrong TV audio codec – mp3

Hi,

I am running Kodi 16.1 on Debian package version: 16.1+dfsg1-2~bpo8+1. Platform: Linux x86 64-bit with MythTV 0.27 (only alsa, no pulse audio).

I have a little problem when play LiveTV. The TV channels are usually encoded as MPEG Video and Audio, but the audio is handed over as mp3 stream and I face a stuttering every few seconds:

Code:
22:24:10 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 1 packets of duration 24
22:24:24 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 3 packets of duration 24
22:24:24 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 2 packets of duration 24
22:24:39 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 4 packets of duration 24
22:24:39 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 2 packets of duration 24
22:25:02 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 3 packets of duration 24
22:25:02 T:139978884671232  NOTICE: CDVDPlayerAudio::OutputPacket duplicate 2 packets of duration 24

Full kodi.log can be found here.

I have two Kodi clients (one linux Debian, one windows 10). The windows client shows correct audio stream and no stuttering. The linux client always shows mp3 audio and stutters.
I guess that MythTV is not source of the problems and due to two different clients my suspicion is that linux client is somehow broken. Can you help me?
