I am creating some videos to upload to Youtube. I am having a problem with audio. I am creating and uploading using Adobe Premiere CC and Media Encoder. When I upload the video to Youtube, I have no issues. The problem I am facing is when I play it on mobile phone, I get now audio tracks (vocal) playing through the phones speaker. I do get the audio track I rendered through After Effects. However, I can hear the vocals On a PC, Ipad etc. I can hear the vocals through a headphone plugged into the phone or via bluetooth. I am using the H.264 codec with youtube 1080 settings. Any suggestions and yes I have tried a different phone to see if it was and issue with the phone.
your issue here sounds like the smple rates arent the same. The music and V/O need to be the same sample rates. You can change the sample rates in sequence settings. Just change it to the lowest of the track rates.
