Echo Layla3G Question/Problem

Hi there

Is anyone using an Echo Layla 3g soundcard ?

I have just installed one and the sound quality is really good except that I
get random popping noises which renders it useless to me.

I have spoke to Tech support and they have suggested a few things all of
which I have now tried lowering 'hardware acceleration and colour quality to
16 bits.

I did have an NVIDIA graphics card which they suggested may be the cause of
the problem so I have now changed that for a Matrox Millennium G400 dual
head. (fortunately borrowed as it hasn't worked'

I have tried increasing and decreasing buffer size 512 is the default
setting giving a latency of 12. something ms.

I have a Pentium 4 - 3gig chip and an ASUS P4P800 motherboard. 1.5 gig of
RAM.

Any suggestion would be welcome as I can't speak to them again until
Tuesday.

Many thanks

Martin
