Thanks for your answer. Latest HG does not compile on my system, throws
memalloc.c errors. (Could be me doing something wrong though - out on a limp)

 CC [M]  /home/bvdm/alsa-driver/acore/memalloc.o
/home/bvdm/alsa-driver/acore/memalloc.c: In function ‘snd_mem_init’:
/home/bvdm/alsa-driver/acore/memalloc.c:729: error: implicit declaration of
function ‘proc_create’
/home/bvdm/alsa-driver/acore/memalloc.c:730: warning: assignment makes pointer
from integer without a cast
make[3]: *** [/home/bvdm/alsa-driver/acore/memalloc.o] Error 1
make[2]: *** [/home/bvdm/alsa-driver/acore] Error 2
make[1]: *** [_module_/home/bvdm/alsa-driver] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.24-16-generic'



I see references to similar errors on the list, had to do with processor
identification?


Configure detects this:
checking for processor type... i586
checking for i386 machine type... default

/proc/cpuinfo starts with:
[...]
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 72
model name      : AMD Turion(tm) 64 X2 Mobile Technology TL-50
[...]



I have also just lifted patch_realtek.c from the current hg and compiled it in
a working tarball (actually labelled alsa-driver-hg20080502.tar  from the
realtek site), which compiles, looks a bit better. 
Gives me: 
 - Different set of mixer controls (not 5.1 though)
 - headphone output in the strange dual-use SPDIF jack only (headphone jack 
only goes 2/3 of the way in)
 - but with jack-sensing working in that jack, with the boxes turning off when 
I insert the headphone into the SPDIF.

Cheers, B.
