No sound when launching StarCraft2

Hello,

I'm trying to run the winepak of StarCraft2 on the elementary OS Loki.

The game launches and performs fine, but there's no sound.

I have updated to the latest version of winepak, but when I launch the game via the command line, I see the following errors:

ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

wine: Unhandled exception 0xc0000417 in thread 71 at address 0x523586 (thread 0071), starting debugger...
wine: Unhandled exception 0x80000003 in thread ec at address 0x130d60d3 (thread 00ec), starting debugger...
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory

Is there any way to have this fixed?

I got it to work in both Loki and Hera doing:

flatpak install --user winepak com.blizzard.BattleNet.BaseApp
flatpak run com.blizzard.BattleNet.BaseApp
# Make a first run of Blizzard launcher normally, then close.
flatpak repair
flatpak install --user winepak com.blizzard.StarCraft2

Everything works fine. Hope it helps.

Cheers.
