No insights, but I confirm the bug with a TerraTec DMX XFire 1024 (CS4624).

Hm, cs46xx driver hasn't been much changes since long time ago (around
year 2005).  The only big change was about some PM fixes, and I don't
think it's relevant...  Could you run als-info.sh to get the status?

At:

http://pastebin.ca/939784

Script was run just after repeating the problem. I have two of these same 
cards (TerraTec DMX XFire 1024) by the way and the same thing happens on 
both. If desperately need be, I can also test a CS4630 in the form of a 
TerraTec SiXPack 5.1+.

This may indeed have been broken for a long time. I (sometimes) use this 
card in a little P1-133 machine in my living room to feed music to my 
regular amp and, seldomly, use it to record from for example LP.

Last time that I did was some 2 months ago and I experienced the problem and 
at the time I remembered seeing that problem before, which may well have 
been 2005. As said, it doesn't happen each time and I use recording on that 
card seldomly...

I expect this is going to be difficult to debug. It's no doubt a timing 
problem and yes, Gadi's description matches. This is what a bad capture 
sounds like:

http://members.home.nl/rene.herman/cs4624-bad-capture.wav

(a good capture is just, well, good)

Didn't report it before since when I'm recording on that thing I'm recording 
for someone else and when I'm busy trying to do something _with_ a computer 
instead of _to_ a computer, all those pesky little linux problems just get 
on my nerves so incredibly bad at times...

The output seems truncated.  Could you give the generated file via
"alsactl -f somefile store", just to be sure ?

Is the original data also truncated at the middle or is it a paste.bin

Well, the content is now full but I mean to adjust "ADC Volume" to the

No change. Also no change with capturing at 48000/16/2 (previous 44100/16/2) 
nor 44100/8/2, nor 44100/16/1.
