Yes, the details were reposted to alsa-devel a week and a half ago.
(I have no idea what "sound-hackers" is, or whether you're reading this from
that list or the Alsa list, or what list I should post to. I'm just sending
this to you and alsa-devel.)

Hi... I hope you can help me. I'm replying to a message about a month old,
but I just decided to try Alsa 9 again.
My sound card is a Shark Predator ISA. It's pretty obscure (I had to send in
a patch to get it recognized). It works fine in Alsa 0.5 with the ad1816a
driver. It also works fine with oss.
I am running Mandrake 8, kernel 2.4.3-20mdk.
Using 0.9.0 beta 9, Alsa malfunctions in the following way:
-- If I go to alsamixer, I find that the sound gets louder the *lower* I set
the volume, so it's loudest at 0 and can't be heard at all at 100.
-- aplay <filename> only plays the first half second of the sound, which
keeps repeating over and over. A couple of seconds later I get this error:
aplay: pcm_write:934: write error: Input/output error
The sound does not stop and keeps repeating until I actually stop Alsa.
I compiled the driver with debug; /var/log/messages shows this:
Nov 19 14:39:42 localhost kernel: ALSA pcm_lib.c:1864: playback write error (DMA
or IRQ trouble?)
Nov 19 14:39:52 localhost kernel: ALSA pcm_native.c:1250: playback drain error (
DMA or IRQ trouble?)
As far as I can tell, my DMA and IRQ settings are correct. The relevant
settings from my /etc/modules.conf are:
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
alias snd-card-0 snd-card-ad1816a
options snd-card-ad1816a snd_port=0x500 snd_mpu_port=0x300 snd_fm_port=0x388
snd_irq=5 snd_mpu_irq=7 snd_dma1=1 snd_dma2=0
