emu10k emits buzzing and crackling

[Benjamin LaHaise]

Hey folks,

One of the workstations I use really doesn't like the emu10k driver in 
2.4.13-ac5.  The box is a dual athlon running rh7.2.  Playing mp3s seems 
to work well, but other samples from xfce on shutdown and window close 
result in buzzing and popping noises.  If anyone wants details or patches 
tested, drop me a note.

You may want to try the cvs version, but I thought they were pretty close
to being in sync.  I have the same setup as you(dual Athlon, RH7.2) and
I haven't seen any problems as of yet.

I've also experianced this with 2.4.13+preempt. As ben said, playing single large files
works fine, but when playing short files or using esd for short bursts of sound, I often
get popping noises.

I'll give the cvs version a try and report back.

I'm seeing something similar on RH7.2 with the emu10K driver.
Except XMMS and the cd player result in nothing but noise, but
the window manager events sound fine. The volume of noise
from XMMS/CD player can be controlled by the mixer.

Machine is a dual P3-450, GX chip set.

I saw this with both the base RH7.2 kernel and the latest RH
kernel (2.4.9-??). RH 7.1 worked fine on the same hardware.
I tried playing with mixer settings and IRQ settings with no difference.

That's very interesting as the driver shipped with rh7.2 works fine on 
my card.  Are they different revisions of the card?  Could you post your 
startup logs for the driver -- perhaps we can find some pattern to this 
and make some kind of quirks mapping.

Here is my startup:

Creative EMU10K1 PCI Audio Driver, version 0.16, 14:36:54 Oct 27 2001
emu10k1: EMU10K1 rev 4 model 0x21 found, IO at 0x1c00-0x1c1f, IRQ 16
ac97_codec: AC97  codec, id: 0x5452:0x4103 (TriTech TR28023)

I should also mention this is kernel 2.4.13 with the latest cvs emu10k1 
driver.
I have no problems with it.

Which program is used to play these?

With the emu10k1 there is no need to use esd...

The current emu10k1 driver uses a hardware clock to generate periodic 
interrupts. These apparently ran at the wrong rate in some Alpha machines.
It's possible that the same problem occur now with more recent i386 
machines.

emu10k1 provides in-kernel support for multiple userspace apps sharing a
single /dev/dsp0 connection?  :)

GNOME pretty much requires esd, like KDE requires arts.

The hardware has something like 512 channels. esd sadly wont make sensible
use of this. I'm not sure if Arts will

Expect gnome to be using arts soon

Yes. :) :)

For most common sound cards. Not when you can have 32 independent stereo 
sound streams.

You still need esd/arts. You can't play remote audio otherwise.

Oddly enough whilst looking for updated esound sources, I came across
Advanced Sound Daemon (asd), on freshmeat.net. It's said to be esound on
steroids, capable of multiple input and outputs.

I have the same problem. It started when I applied Gerd Knorr's V4L2
patches for bttv 0.8.x in 2.4.12. If I reverted back to the vanilla
2.4.12 kernel, all was fine.

This then became a problem in vanilla 2.4.13. It doesn't happen with all
apps, just apps that play small wav files (like "play"). Quake3 and xmms
don't have any issues.

I've tried the drivers on opensource.creative.com, but they haven't
helped. I'm now using the V4L2 patches for 2.4.13, and the problem is
still there.

Here's my driver info:

Creative EMU10K1 PCI Audio Driver, version 0.16, 23:24:09 Nov  5 2001
PCI: Found IRQ 7 for device 00:0c.0
PCI: Sharing IRQ 7 with 00:07.2
emu10k1: EMU10K1 rev 8 model 0x8027 found, IO at 0xe400-0xe41f, IRQ 7
ac97_codec: AC97  codec, id: 0x5452:0x4123 (TriTech TR?????)

Please CC any response to vi@sh.nu, as I'm not on the list.

Thanks,
