--- Comment #32 from Markus Linnala markus.linnala+winehq@gmail.com --- SC2 updated 2018-09-05 and again 2018-09-12 and it is now v4.6.1.68195. battle.net is now v1.12.3 build 10491.
Wine is my own build, essentially 3.15 staging with PBA.
I have not had issues with audio after first mentioned SC2 update. I have not done overly too much testing but I guess problem should have occurred once or twice.
I still guess this issue is still valid, but current program timings make it happen less than previously.
