'clicking' noise in Gran Turismo 2 @Ubuntu 8.04

[saturday]

both - PAL and NTSC versions have clicking noise with certain cars, for example Viper in super license 7 (others I can remember of: Lotus Elise, Corvette Coupe in arcade). The click differs slightly depending on the car model.
I tried different latency settings for sound - didn't help.
BIOS versions tested: SCPH-1001 and SCPH-101

pSX version 1.13

WAV file 3.7MB:

haven't completed game yet (only licenses and a bit arcade) so can't tell how many car models have this 'click' noise

NTSC
arcade - SCUS_944.55
simulation - SCUS_944.88

PAL
arcade - SCES_023.80
simulation - SCES_123.80

Hmmm, it sounds like it needs a latency adjustment, but as you said you tried doing that. Does this occur on either the Original Disc or a Disc Image?

actually if it were latency issue, the sound would just skip, in this case you can hear periodic clicking, everything else about sound seems normal

no difference, if it's cd, .bin/.cue or .cdz
I tried pSX windows version in wine, but that segfaulted. I'm going to test other playstation emulators, but that will take time, cause I only have pSX 1.13 right now

ok here we go:

epsxe Corvette Coupe (P.E.Op.S. Linux OSS Audio SPU Version 1.9) = no clicking noise

compare:

pSX Corvette Coupe (the car can be played straight away on arcade disc) = clicking noise
