[GI-XPEED LX3] GI LX3 Audio Loss

[handy]

My box seems to lose audio for 3-5 seconds.
This seems to happen on pay channels as well as Free ones.
I have 2 sat tuners on 28.2 and 2 DVB-T2 on freeview, the audio loss is on both sat & freeview, it does not happen very often (once or twice a day), but extremely annoying when it does.

Would this be software or hardware issue?
