[PD-dev] alsa rme pd again

[Orm Finnendahl]

Hi all,

concerning the RME and ALSA issue, there now is another solution:

I got the new RME card and since jack doesnt't work properly on my
laptop, got the idea to adapt pd to use Bill Schottstaedt's sndlib for
better ALSA compatibility. Stefan Kersten helped and wrote the patch 3
weeks ago. It works without any problems (I used it in 2 concerts and
a 1 week installation workshop).

The patch makes pd work with all cards, which work with the snd
program of Bill Schottstaedt (also the RME 9652). For the Hammerfall
to work you have to set an environment variable
$SNDLIB_ALSA_PLAYBACK_DEVICE to "default:0,0". This is an ALSA
software layer which converts the interleaced samples into non
inteleaved. And of course you need to have the sndlib installed.

I could send the patch but would prefer Stefan doing it, as it's his
work and he only sent me a preliminary hack shortly before I had to
head off for the workshop.


Yours,
Orm

P.S.: It might be a good idea to add a configure flag like
--with-sndlib to compile pd against this library for future releases
as it seems to be a cleaner interface to ALSA than the old pd code.
