The sound is little choppy even with native OSS drivers for me (built in CS4610 card), artsd makes it better quality, but has some delay.

I have changed the size of artsd buffer
artsd -S 4096
and now sounds great, no more choppy (but with some delay)


PD: i'm using artsd with all this options:
artsd -F 20 -S 4096 -a alsa -d -s 1 -m artsmessage -l 3 -f

Well, with ALSA 1.0.0, sound is choppy anyhow. ARTS and artsdsp act as a separate software mixer and will therefore use up large amounts of your CPU and make your sound choppy in some cases. I would reccommend just getting a better card.

i try artsdsp -m vendetta
and when i do play it say:
Fatal Error: Couldn't open window.

with artsdsp -s -m vendetta (-s use the single-threaded version)
it works but the sound is all the time cropy

any ideas???

I have this problem in vendetta with alsa-oss too. I don't know is something wrong with alsa or vendetta, both are possible. To run vendetta with asla-oss, corresponding module should be loaded, then run artsd:

artsd &; artsdsp -m ./vendetta

This way it works fine.

ALSA team just released a new version (http://www.alsa-project.org/), changelog says that they fixed a bug with OSS emulation, I wonder if it will remove the problem with vendetta?

Hi. I'm running 2.4.22 kernel with debian patches + alsa (snd_via82xx) + oss emulation. When i run vendetta i get no sound and i this error msg:
/dev/dsp: Input/Output error.
OSS emu is fine, mixing is fine too. I can play from alsaplayer+xmms(oss)+xmms(alsa)+mp3blaster(oss) at same time and everything works fine. ALSA version - 0.9.6.

Do you have arts/esd runnig?

Please search back a couple of threads which talk about this problem specifically. You are running into a problem with Alsa's OSS emulation and vendetta mmaping /dev/dsp.

i'm using the same system but with de kernel-2.6-test9
and with the last update start working again.

But still not work the sound.
it returns:
/dev/dsp: Input/output error

I have 2.6-test9. I can probably help you more here. Did you include the ALSA and ALSA-OSS modules in the kernel, or modularize them? Does /dev/dsp actually work? If not, did you even mknod it?

i have include support for oss emulation
and it's working right with others app
like
alsaplayer -o oss -d /dev/dsp

I figured out how to unchoppify the sound WITHOUT arts. It's the "snd_mixahead" variable in Vendetta. This is what I did:

/set snd_mixahead 0.75

Now it's perfect! The default is 0.5, in case you ever need to know.

Cool!!!

set snd_mixahead 2.0

worked for me. I guess the value depends on your box perfomance.
