If you look at it from a windows perspective, you would do a
iterate over the devices doing a waveOutGetDevCaps to get the device
name. One of those
devices would be the preferred device and somehow windows sets that.
You can do a
waveOutMessage with DRVM_MAPPER_PREFERRED_GET to get that device. You
can currently get the number of devices and iterate over them using the
OSS driver. We
don't have a way of specifying which is the preferred one. You can
specify it in Direct
Sound but that doesn't apply to the wave device.
The ALSA driver is another issue. It only supports a single device and
you have to
specify it manually. You also have to specify how you want to open it
using the device
name plug:dmix or hw and also specify which sound card if there is more
This doesn't map well to the windows way of doing things.
I'm not sure what the best solution for this is because they are really
Throwing in the other drivers complicates matters even more. It would
be nice to solve
this problem in a driver independent way.
