Audio drop outs when other user are accessing the Samba Server

Hey All,

I come across an issue with the Audio Passthrough dropping out.

1 - Setup samba server with a hard drive - SATA (I used a 4 TB drve)
2 - Use ZDMC the play a 720p file
3 - have another user access the samba share and play or transfer files.
4 - ZDMC audio and video will go out of sync. then audio will drop out then it will fix dropout again to get back in sync.

if there is a way to give HDD Priortiy to ZDMC over the Samba server?

Thanks
