Hello, trying to use channels 4-flag with rme-driver (-32bit) gives me the following error
/dev/dsp1 (read/write): No such device (now will try write-only...) /dev/dsp1 (writeonly): No such device /dev/dsp1 (readonly): No such device
Obviously pd is trying to use a second device which is not supported according to Guenther Geiger's driver-readme. pd-0.36 worked fine .......
Greetings Michael

I thing to get the full potential out of RME cards you probably should use ALSA. If it doesn't work directly in Pd, using the jack-output is the way to go. But I don't have a RME, so I'm just guessing from what I read on other lists...

Hi Frank, I tried it once (alsa/jack/pd) and it can't compete to Guenters driver. I wouldn't risk it in the live enviroment I am going to use it in Thanks anyway, greetings Michael

Guenter's driver is and always has been the best. But alsa is where it will be at in the future; I'm not sure whether it will be possible to run Guenter's RME OSS driver in future versions of linux. so one way or another we've got to figure out how to get the alsa RME driver to work adequately with Pd...

:) Thanks I have to add that writing this driver was only possible due to the work of Winfried Ritsch, who wrote the mother of all Hammerfall drivers. It has been the base of my driver and the ALSA Hammerfall driver. Winfried was actually the one who brought the first high quality soundcard to the Linux community.
But alsa is where it will be at in the future; I'm not sure whether it will be possible to run Guenter's RME OSS driver in future versions of linux. so one way or another we've got to figure out how to get the alsa RME driver to work adequately with Pd...
Yes, we were hoping that portaudio would solve some of these problems, but if you take a look at the homepage of Josh Haberman, who wrote the ALSA support for portaudio, you will see that he had a hart time too trying to get everything under one hat.
From a programmers point of view, the ALSA API is still incredibly
hard to handle. The documentation is only useful for writing toy applications. It seems that you have to be an ALSA developer to really achieve good performance.
I have a version of the pd alsa part that works with the Hammerfall, but I was not able to achieve the same performance as with my driver. Additionally this version shows problems with some cards, so I surely have done something wrong.
We need someone who is willing to really dig into ALSA, probably by reusing code from the JACK alsa driver. My motivation for doing that is pretty low, because for desktop usage I am happy with JACK, and for performance critical situations and installations I use my own driver.
Thats the situation. Maybe we can give out a call for help among the Linux audio developers community, there must be someone who is wants to contribute to a established system instead of writing the 200ths software syntesizer.
Well,
Guenter

Hello,
Guenter's driver is and always has been the best.
thats true, since he invented the multichannel OSS-ENhancement.
:) Thanks

It didnt want to anounce it yet, but just today I got the new RME HDSP-MADI 64-Channel Digital IN/OUT and 64-Playback/Capture ones (incredible, the mixer has 8192 volume items) and we decided I should to do an ALSA-Driver for it, so anyway I have to dig into ALSA. On the way I will have a look ob the HDSP-Card.
So I can try to make an ALSA-Lib-part also respecting this card for PD. Since I think also, ALSA has a lowlevel and midlevel-driver + alsalib for controlling the cards and that should be enough function Calls ;-)) (but most of all dependencies) ( not using portaudio to play in jack to control alsalib...)
Since ALSA is now in linux-kernel. it should be quite stable in development.
(If above doesnt work out, I can make a OSS/Free guenther-like driver for the cards. ;-)
Hoping for enough beta-tester on this list.

Yes, it seems that pd 0.37 is doing something wrong with multiple channels and the OSS driver. You can try to start in 2-channel mode and change the number of channels with the media menu, but thats not a perfect solution.
Seems to be a bug that has been introduced by the recent changes to the pd media system.
As Frank said, you might try using ALSA, but be aware that pd doesn't support the Hammerfall ALSA API. So you will have to use JACK and the PD JACK driver.
Best,
Guenter

Thanks Guenter, I did not even realize, there is a new menu ...... My problem now is: how to run it in nogui-mode?

if somebody has the same problem: changed default setting in s_audio.c : works
