[PD] Can't get PD/RME9652 even close to working

[Nick Rothwell]

I'm trying and totally failing to get PD working with a Hammerfall 9652.

(System: Red Hat 7.1 - kernel 2.4.2. Using the PD 0.33P2 RPM.)

The rme96xx module doesn't install cleanly. "make install" seems broken
due to a macro fault in the Makefile:

	install -m 644 rme96xx.o /lib/modules/#include <linux/rhconfig.h>/kernel/drivers/sound
	/bin/sh: linux/rhconfig.h: No such file or directory

I copied it by hand, but got complaints about unresolved symbols
when doing a modprobe/insmod. Sometimes it seems to work, sometimes
it refuses, sometimes it complains "No such device". The docs claim
that this module release is compatible with this kernel version.

The rmectrl program doesn't seem to work either: the X11 version shows
lots of options but they can't be changed. In fact, they're also
wrong: the card is shown at 48KHz when my Roland desk has clearly
locked to it at 44.1.

The ALSA support in PD doesn't match that which comes with Red Hat 7.1
so I get:

	warning: Pd compiled for Alsa version 0.9 appears to be incompatible with
	the installed version of ALSA.  Here is what I found in /proc/asound/version:
	Advanced Linux Sound Architecture Driver Version 0.5.11.
	Compiled on Aug 27 2001 for kernel 2.4.2-2 with versioned symbols.
	snd_pcm_open (input): Sound protocol is not compatible
	snd_pcm_open (output): Sound protocol is not compatible
	audio I/O stuck... closing audio

Tried building PD from source, specifying --enable-rme.
So tried "pd -rme" which gives:

	RME9652: failed to open /dev/rme9652/C0da1 writeonly
	RME9652: failed to open /dev/rme9652/C0ad1 readonly
	RME9652: configuring 0, fd=0, sr=44100
	, dac=0
	RME9652: Could not set sampling rate for device
	RME9652: Could not set DSP format
	RME9652: Could not set channels
	RME9652: configuring 0, fd=0, sr=44100
	, dac=1
	RME9652: Could not set sampling rate for device
	RME9652: Could not set DSP format
	RME9652: Could not set channels
	RME: ioctl on output device 0 failedRME: ioctl SOUND_PCM_GETOSPACE says 1 buffsize
	audio I/O stuck... closing audio

Where do the /dev entries come from? MAKEDEV doesn't know about
them. Does this require a kernel build?

(Aside: PD's "make install" is broken if /usr/local/include doesn't
exist; it creates it as a plain file and breaks gcc.)

Built with ALSA 0.5x, PD gets are far as trying 1 input/1 output and
then just gives screeds of file descriptor error messages.

Would someone please try to persuade me that I'm not just completely
wasting my time?
