Problem is, sound isn't broken, OSS works fine.
If OSS can work, why would sndio just hang?
I also couldn't find a way to get an error message to the user in case something is wrong, for example the documentation says that in case of error sio_write returns 0, so it is not even possible to detect errors?!
Why in all the world doesn't it use -1 to indicate an error like write()?
Then at least we wouldn't just hang but could get some message to the user and/or drop the data  to continue playback without audio.
