Thanks for providing the log file. I don't notice anything different between the 2 runs, so it's not something related to a configuration.
Try removing pulseaudio completely then reboot the system, this might get rid of any PA interference.

Excellent thank you!

Actually, it did work but instead of adding these lines I uncommented the same in the config file and just changed the values. Thank you very much for you fast and adequate response.

Yeah. I guess you're right.

THe standered emulator works ok with slowdown and glitches. The other emulators ether back out or just get sound. IDK why. The guy reccemended one emulator but it doesn't work for me.
