Post by bach »

Hello,

i'm new here. Thank you for the great work you've made !
I am on archlinux and i manage to compile sheepshavers from macemu repository with --enable-sdl-video --enable-sdl-audio, launch and install Mac Os 9
My probleme is that i have no sound from OS9
My sound setup is working well through archlinux but sheepshavers is saying

Code: Select all

$ sudo ./SheepShaver

Are you using ALSA on Arch, or do you have it set up to use PulseAudio or something else?

SDL-Audio is specifically looking for ALSA. You may need to do some tweaking there.

i am using pulse audio over alsa
i tried to run

Code: Select all

sudo padsp ./SheepShavers
without success

i also tried sheepshavers compiled without sdl-audio but with the same results

would you have an idea of what tweaks ?

ok i managed to get sound output from sheepshavers os 9

i made that
Set memory access
Due to a change in how programs in Linux are allowed to use memory, before using SheepShaver you need to set a variable in the file
/etc/sysctl.conf
Add this line: vm.mmap_min_addr = 0
restarted

and launched sheepshavers (compiled withour sdl) with padsp but without sudo

Code: Select all

padsp ./SheepShavers
