On 2.2.3. I used the alsa-driver suite for sound. No problems:
Configure, compile install in one go.
Same on 2.2.4.
Until I called a FAX decoder software for HAMs, which runs fine under
2.2.3 with alsa.
I recompiled the alsa stuff for 2.2.4.
A strace of a call of the fax decoder program (acfax) show the follwing:

write(2, "do_receive: I/O error\n", 22) = 22
_exit(1)
For me it looks like some problems concerning /dev/dsp,
cause the software (acfax and the alsadriver) run well under 2.2.3 and do
recompile under 2.2.4 without problems, but get one when executed.
Any comments?
