[solved] Nvidia bumblebee hybrid: No sound on wine games

[ibrahem]

When running:
sudo optirun wine64 ./game.exe

The game runs with accelerated graphics
,but with no sound

When running:
wine64 ./game.exe

Sound is ok, but graphics not accelerated

EDIT: adding more details:
I am using non-free driver
it is: video-hybrid-intel-nvidia-390xx-bumblebee
I installed it with: sudo mhwd -a pci nonfree 0300
My GPU is: NVIDIA GK208BM [GeForce 920M]
I am on DE: KDE

use the non-free drivers. don’t expect that bumblebee is a proper alternative. sometimes it does sometimes not. it’s a gamble with bumblebee.

I am already using non-free driver
it is: video-hybrid-intel-nvidia-390xx-bumblebee
I installed it with: sudo mhwd -a pci nonfree 0300
My GPU is: NVIDIA GK208BM [GeForce 920M]

the problem happens due to “sudo”
sudo optirun wine64 ./game.exe

I had to use sudo because when I run optirun wine64./game.exe
I get a message says that I have no permission to communicate with bumblebee deamon
and I have to be in bumblebee group

so I ran: sudo gpasswd -a $USER bumblebee
to add myself to that group
then: reboot

then when running: optirun wine64 ./game.exe without sudo,
the game finally works with accelerated graphics and sound is OK
