Log Message:
If we are using the pad audio device, there must be a process with
the corresponding pad device open, or we get EIO from audio accesses
Explained and fix provided by Nathanial Sloss <nat@n.o>
Note: if we are testing and using real audio hardware, the open
of /dev/pad0 is irrelevant (but harmless, so we don't attempt to
check) and what's more it doesn't matter if it succeeds or fails.
If we're testing under qemu (or any other situation where the only
audio "hardware" is pad) then the open will work, and there should be
no more EIO.
If there is no audio hardware of any kind on the system being tested,
the attempt top open /dev/mixer should fail, and the test will be
skipped.
