Hi,
I'm a happy user of xmame :)
The only problem with it is the sound. The sounds are cool, but much to slow
(high latency).
I contacted the maintainer of the xmame-project (Hans de Goede), and he told
me that more FreeBSD-users have problems with xmame and sound. In the mailing-
list-archive I could not find anything about this problem.
I use Luigi's sound driver (pcm0), with this kernel-config:
device pcm0 at isa? port ? tty irq 5 drq 1 flags 0x15
Some examples when starting xmame:
-fragsize 4:
Setting fragsize to 8, numfrags to 5
Fragsize = 40, Numfrags = 1632
-fragsize 128:
Setting fragsize to 256, numfrags to 5
Fragsize = 256, Numfrags = 255
It seems that when xmame.x11 asks a fragsize of 128, FreeBSD doubles it. And,
worse, when xmame asks a numfrags of 5, it doesn't use that number of numfrags
either.
Hans told me that this is the reason of the poor sound in xmame.
Xmame-version: X-Mame-0.35b12.1
System: AMDK6-233, 64 Mb, FreeBSD 3.1-STABLE (23-4-1999).
Does anyone have a clue?
Thanks,
Pieter
