hi Tobiah

getting slightly OT here - but you've had some luck geting crystal=20
semiconductors chips to run under ALSA?=20
i've got a thinkpad, which i got particularly for doing some laptop=20
techno/electronica... would probably be within this budget too as refurbs=
more affordable in the US than in the UK. nice machine, its a thinkpad 60=
366Mhz, does me just fine... not huge specs but reasonably powerful for w=
im doing.

problem is i'm really struggling with getting sound happening, i'm very c=
- - running 2.5.9 kernel with ALSA - i've read everything on the web abou=
configuring sound for a tp600e and still am not quite getting there.

so i just wondered if you'd had any experience with this on a thinkpad - =
whether you know of any problems / workarounds for the cs chips which you=
used in setting up your Dell .

thanx and best wishes
