I've some problems with audio tracks on some channels. no matter if channel is dvb-s or iptv, problem is the same on both medium.
I have iptv stream. When I play it in vlc player it works perfectly, I have to audio strems.

I've added this stream to IPTV in tvheadend. When i try to play this channel form tvheadend i have isse with pol audio stream :(
Vlc says

No suitable decoder module:
VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this.
