Set the number of record and play channels individually -- currently

Browse Source 
we try to set both in one ioctl, to the same value, which fails if not
both record and play direction support that many channels. (Having
more play than record channels is common these days.)
This does likely address part of the problem described in PR pkg/35444
by Mihai Chelaru, and it helped Matthew R. Green about half a year
ago -- see the thread in tech-misc in April.
