Since Yousician's last update, it was throwing an error when initialising audio output. Unfortunately I don't have access to the old version, but they seem to have dropped win<10 support, and are using only IAudioClient3_InitializeSharedAudioStream. They also use IDeviceTopology to get the type of the first output connector.
This is the bare minimum I needed to get it working.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=136765
Your paranoid android.
