Here is my sound card: http://www.soundblaster.com/products/sound-blaster-zx.aspx#specs

At the moment, I have my sound going through a Samsung AV-R620. It does a pretty good job. I have no problem with the sound coming out of any setting, stereo and 5 speaker sound are fine. There is a serious problem when it comes to DTS or Dolby Digital. During the playback of anything that uses either of them, the sound will cutout for moments at a time, randomly. Sometimes it can be tolerable and other times unbearable

I have the sound card connected using an optical cable. I have tried other optical cables, but I get the same result. Hooking the sound card to my Pioneer EF-DHP800 headphones will still cause dropouts, buy nowhere near as often. I've tried going through the sound settings and SPDIF properties through windows and I've used different players.

I think this may have something to do with the signal coming through the sound card.

I've had had my ps3, ps4 and XBOX 360 output DTS/ Dolby Digital to the AV receiver with no problems. I do have my tv connected by digital AUX (digital sound is horrific, but I think that's down to the tv).

I've tried looking for a solution, but have yet to find one.

Oh. Almost forgot. I have updated the drivers.

I have solved the problem. I will share the answer in case it helps anyone else.

I downloaded the program from the following link:

http://www.thesycon.de/deu/latency_check.shtml

Running this program showed me that I was having latency problems. Next I had to find out why. I then downloaded LatencyMon (http://www.resplendence.com/latencymon). This one suggested that there was some kind of throttling with my cpu. I went to the advanced settings in power options and checked the cpu settings, there was nothing I could see that I could improve. I then changed the profile from "Balanced" to "High Performance". This seems to solve the problem.

I finally have digital surround sound without audio cut outs.
