ah well... not that then.

The last version I tried the back-port with was 2.2.18p20-ben1 (IIRC?) and
it worked then... since then I've been off-line...

So you might check the diffs between 2.2.18p17-20 and the final release.

It definitely worked built in and as module on the version named on my Linux
page... - having got caught out ;-) - I am now religious about testing my
stuff both built-in and as modules before posting it...

BTW:

I was not intending (when I do get back to it) - to work any more on 2.2 -
since there seems to be "0.5 * sqrt(damn_all)" chance that the back-port
would ever make it in to the 2.2.x kernel.

The intention is to work on things for 2.4/5/ALSA

- but if there's a few people who want a consolidated back-port for 2.2.18 -
I will do it... although it really needs to be hosted somewhere else if it
is going to be a long-term thing.

ciao,
Iain.

well, that will still require a complete re-write of the mixer abstraction -
even if sound out does not take too long to achieve.

I think, someone has already started on the mixer abstraction.. there was an
exchange on this list a couple of weeks back about it...

and, of course, there is no sound in..

Hi Hollis et. al...

it's probably a silly - like forgetting to call the init from within
drivers/char/mem.c  (that change has been made several times by both me &
Geert) but it seems to slip out of the diffs somehow)...

I will be back on the case as soon as poss (maybe after this month).

There's obviously lots still to do to get full duplex working properly for
2.4.0 - from other reports... and a niggle in my mind that says "maybe some
of the dbdma traffic I've seen on the list might have an effect on the
flakinesss (or otherwise) of the dmasound driver..."

(and also there's the start of an ALSA version - from a posting on the
ALSA-dev list yesterday)...

- I'm just still bogged down in "work-that-pays-the-rent" :-(

ciao,
Iain.

With the latest versions of esound (0.2.22), xmms (1.2.4), and running
kernel.org's 2.2.18 final, I was *still* getting the
sound-plays-way-too-fast bug, in xmms, mpg123, and myth2 (all of which use
esound).

Following Henry Worth's emails from a while back, I tried the 2.4 dmasound
backport (http://www.drfruitcake.com/linux/linuxppc.html). It mostly
applied (one Makefile needed a little tweaking).

With dmasound built in, nothing happened at all. /dev/sndstat said no such
file or directory, mixers wouldn't work, and AWACS didn't even show up in
the interrupt list.

However, with dmasound as a module (and 'alias sound dmasound_pmac' in
/etc/modules.conf), everything (including esound) works perfectly.

So:
- 2.2.18 final and esound still don't play well together
- the 2.4 dmasound backport doesn't work compiled in (and probably could be
  updated for 2.2.18)
