While my laptop (beta7) works normally, two other 5.3beta systems have
volume settings which no longer work, but ogain does. ogain (output
gain) seems to have replaced volume. Volume does nothing, but the mixer
works on all three systems by using ogain.

One system with the change has an AD1885 and an ICH2 and the other uses
PCI snd_es137x. The working system has an AD1881A with an ICH3. I won't
claim to know why the AD devices behave so differently. The one where
Volume still works does not even have an ogain.
