No Audio When Casting Tab

[Lex Luthor#WN]

I'm trying to play videos off my PC by loading the file in chrome and then using the chromecast plugin to cast.

I haven't yet found 1 video that will play sound. When using chrome on the PC, I hear sound on the PC, then once I cast it, sound stops on the PC and I don't get sound on the TV.

I've tried .mkv and .mp4. I've converted an .mkv/ac3 to .mkv/aac and .mkv/mp3 and neither plays.

Does anyone have a sample/reference file that definitely plays from chrome on the PC to the chromecast on the TV with sound? If that works, then I know it's just the file formats I'm trying.

I get sound when casting netflix and youtube.

I connected my TV using an optical digital cable to my amplifier. Then switched my amplifier source to TV and hey presto I could get sound via the amp !!
