Topic: SVPCast and Multichannel Audio
Hi team
I'm having an issue where I'm unable to cast files with multichannel audio to my Google Chromecast (newest/Google TV version) or LG TV. If the downmix option is unchecked, multichannel audio files stop streaming abruptly after 13 seconds - the chromecast buffers then the stream stops. Starting a HLS stream does the same, which suggests to me it's an issue with the transcoding/audio and not the end device:
