[Linphone-users]Warning: Soundblaster PCI 128 - different models

[Ekkard Gerlach]

Hello, 

pay attention: using kernel modules for 
Soundblaster PCI 128  there are big diffenences 
in jitter delay on LAN network (only 2 PC's, 
not other traffic):

 1. Soundblaster PCI 128   Model 4700 : minimum 2 seconds 
    delay 
    Chip: es1370
 2. Soundblaster PCI 128   Model 4810 : about .5 seconds 
    delay 
    Chip: es1371
 
I set down number of buffered milliseconds to bottom
 (60 millisecond). I own model 4810 two times and 4700 
for one time. I tested the cards with each other.


Maybe that kernel modules for es1370 are implemented badly. 
Alsa-modules have problems with my 2.4.19 kernel (origin
is Suse 7.2, 2.4.4) . Maybe 
that alsa works when I try once again. (But not now)

Next test ist that I compile sound support and es1371 into the 
kernel, not as module like now. Hope that jitter delay 
will be less than .5 sec. 

Using linphone 0.9.1 (rpm-version , taken yesterday from
linphone server)


any comments?
