Thanks. I found a couple of other too :

<long rant>

however the whole thing is turning into the usual nightmare. The i810 
based sound built on my Epox 4DB2+ mobo is bad - well support seems to 
be a little bit crap, with crackly sound and this weird bug where dsp 
vol drops and needs to be constantly adjusted via xmix to come back to 
life again. This might be a debian problem (i synch with testing alot). 
Coupled with the errors like :

$ play audio9.aiff
playing audio9.aiff
sox: Unable to set audio speed to 44100 (set to 47160)

kicking in immediately with 2.4.21-rc1-ac4, after about 30 minutes on 
2.4.21-rc2-ac3 and immediately again using 2.4.20-wolk4.1s and I'm now 
thinking I should have just nipped out and bought an old Soundblaster on 
saturday. This thing /can/ do 44100 (what cannot) but it looks like some 
internal driver bug causes this - there's plenty of i810 updates in 
recent kernels.

Next I'm grabbing sound from a tape deck into my Octane. Running 6.5.15f 
would you believe there's little-documented problems with audio file 
generation. Dah!! Yep 6.5.14 had movie file bugs, 6.5.15 has audio files 
bugs. So I tar up anything that looks like libaudio on my Indigo2 
running 6.5.17m and wack that over the Octane's libaudio files (fixing 
mips3 and mips4 softlinks where applicable). So now, at least, I'm 
grabbing files which can at least be opened on platforms other than my 
Octane - and that means gwc on my PC because gwc only supports x86 
endieness. So I have to try and process them in  situe (and in silence) 
on my PC, then play them back (over NFS) on my Octane (which is hooked 
up to all my sound gear anyway). Wa! And I still haven't processed one 
gad damn hissy tape.

I'll let you know if these softwares actually do anything :)
