First off Equipment being used.

I'm using vMixHD with the newest version. I have 5 Blackmagic Intensity Pro cards installed in my computer. I'm coming into one of the BMIP cards HDMI from my HD Video Cameras. Coming out of one of the BMIP cards HDMI into a Monoprice HDBaseT™ 1x8 HDMI® Splitter and 8 Receivers. Runing cat6 to all 5 HD Tv's.

My question is, video and audio are going to all 5 Tv's but all 5 Tv's has about a 4 to 5 second delay in the audio. Video starts then 4 seconds later the audio starts. External ouput settings in vMix say audio delay is set to "0". Does anyone have any ideas on why this is happening?

Hi,

Could you please provide a full list of the settings used under External Output and also under the Audio tab.
The problem is usually caused by some incorrect setting somewhere with regards to audio.

Regards,

Martin

Problem has been solved. I had some conflics with other software that was bogging down the audio codecs for some reason. I uninstalled all of those and it works great now. Thanks.

I'm reviving this thread because I am getting audio synch drift also.

It is only happening in the file recorded to the hard drive - the live stream file recorded to the streaming server does not have this issue.

I am recording to MPEG-2 usign the default settings of 30 fps & 25Mbs/sec, since the recorded files are going to local tv stations for rebroadcast.
I am using the licensed SD version.

Any suggestions on how to fix this?

Thanks

What version of vMix are you using and what audio settings do you have configured under vMix Settings -> Audio?

Thanks,

Martin
