Audio issues with Demon's souls inside linux

Hi.
I'm trying to run Demon's souls with lates linux build. But sound glitches are making it literally unplayble.
What I've tried so far:
 - Alsa, PulseAudio and OpenAl
 - Overclocking CPU up to 4.6 GHz.
 - trying all configs. SPU, PPU, Renderer API and ....

my specs:
  - Intel core i5 6600k
  - GTX 1060 6GB
  - 16 GB RAM
  - Archlinux + appimage
When running it, the console spams these:

Code:

[color=#ff6000]U {PPU[0x1000017] Thread (NexusRevolution Main) [0x00a67f94]} sceNp TODO: sceNpManagerGetNpId(npId=*0xd0378864)[/color]
[color=#ff6000]U {PPU[0x1000017] Thread (NexusRevolution Main) [0x00e13e64]} sceNp TODO: sceNpManagerGetOnlineName(onlineName=*0xd0378888)[/color]
[color=#ff6000]U {PPU[0x1000017] Thread (NexusRevolution Main) [0x00e13e74]} sceNp TODO: sceNpManagerGetAvatarUrl(avatarUrl=*0xd03788bc)[/color]

And when I stop emulation it prints these

Code:

E {PPU[0x1000011] Thread (_sys_MixerChStripMain) [0x0154e5a4]} Stat: 'sys_lwmutex_unlock' failed with 0x80010009 : CELL_EPERM [x66368]

Any Ideas?
