I've been working with dual-Opteron machine.
Faster than P4, as Athlons. But as P4, needs use of SSE/E3DNow to really
get some juice out of it.

So is low-latency, LKML people made that clear also about year or two

Well, I didn't remember I made 32-bit mean float's, but neither 24 nor 32
bit mode of my code works. I get alsa errors with both.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/hasas/HASAS/AudioA2.cc?rev=1.2&
with data in upper 24 bits. 16-bit format works and
asking for 32-bit format gives shared memory errors.

cial "release" so that developers really start using it.
To prove ALSA concept you need one stable API (that don't change every six
months) and one stable driver.

jitter is around 3 microseconds in RT-Linux, afaik.
Personally I would make D-class amp's PWM control using some DSP card (with
AD, TI or Motorola DSP processor). PC's CPU would only feed audio data to
that card.

ow does the current behaviour of fixing the version to one used at .src.rpm
build time make it better?
There is still problem on telling users how to build and install the drivers
when they just know how to click mouse in GNOME...

Hello,
Now I think I have converted my ALSA HAL from 0.5 to 0.9 API. What should I
put into device id of snd_pcm_open()? Can't find it documented anywhere.
I think attached patch should be applied to be able to do "rpm --rebuild"
for alsa-driver .src.rpm when updating kernel.

Seems to be now...

I like the OSS documentation. It doesn't tell eve
t as some static version to allow --rebuild of rpm at
kernel update.

;t this done in snd_pcm_prepare() (or something like that)? I think the
snd_pcm_start() should do just the very last piece to actually start the
device.

Yep, OK. I'll look if I can make the l
ct_sync_line(i, card2);
trigger_sync_line(i);
And in kernel space:
for (k = 0; k < i.size; k++)
{
out(start, i.addr);
}
Grr, this is badly starting to look like I'll have to write some RT-Linux
stuff again... I did something like that for DAQ cards a while ago.

I'm thinking of using two M-Audio Delta1010's or one RME Hammerfall cards.
