sound choking with trident driver (SiS 7018)

sound choking with trident driver (SiS 7018)

[Jurgen Kramer]

Hi,

I have a laptop with a SiS 7018 soundchip. While playing music
the sound chokes every few seconds (2.4.19 kernel). I am not sure where
the problem lies. With the ALSA drivers under kernel 2.5 the problem is
not there.

Is there a newer driver for the SiS 7018 (trident.c). The current driver
in 2.4 is dated October 2001.


Greetings,

Jurgen

the -ac tree and 2.4.20-pre1 and onwards (as well as 2.5) contain an
updated trident.c driver. I don't see anything there that is obviously
related to your problems, but you might wish to give the updated
driver a try anyway.  

Thanks and please let us know how it goes,

I have just tried the driver from 2.4.20pre2. No change in behavior. The
sound still chokes every few seconds. Any ideas what might cause this
problem? It doesn't have to be the sound driver.

I will give 2.5 another go.

Hmm.

I've seen this behavour on windwows as well. (I don't have any 
linux desktops with the chipset atm. Servers yes - but we don't
normally install sound drivers on severs ;-)).

The machines I see this on are Athlon 1600XP with SIS5513 chipset
and an AMI bios.

Over in 'dozeland the problem was fixed by turning IDE DMA off, I
had characterised the problem as being due to I/o bandwidth
starvation, possibly due to a poorly set up DMAC. But given it
was doze I couldn't really investigate.

Phaps 2.5 IDE changes are more relavant.

Does information this help? ;-).
