Roku 3800R - No sound in MKV
Posted: Mon May 06, 2019 11:28 pmI too am having audio problems with my Roku 3800R -- I saw that someone else posted about this same model Roku, but with a different sound issue. I tried using the test profile that was posted there, but Serviio won't start with that profile. With that test profile, Serviio seems to be chocking on aCodec="*". If I switch this to aac, ac3, or something like that, the profile will load, but it still won't play audio.
The problem I have is that most of the MKV I have will not play audio. Below is a sample MKVs... I am assuming the sound problem is because most of my MKVs have 6 channel audio which needs to be transcoded down to stereo. My Roku will play most of my MKVs if I just enable transcoding for everything on the server, but I really don't want to do that since I use the same server for more than one TV, and it also occasionally causes lag when I'm transcoding 1080p MKVs.
Can anyone recommend a device profile edit that will just transcode the audio down to stereo?
I tried adding this into the transcoding section of the Roku Media Player profile, but it didn't help.
