ALSA Fireworks driver

ALSA Fireworks driver

[Doug McLain]

Hi Clemens,

I came across your fireworks driver the other day, and would like to get 
involved.  Has there been any discussion on this anywhere or have you 
been completely on your own?  I did a search of alsa-devel and didn't 
find anything, suprisingly.  It seems like native alsa support of what 
seems to me to be the first FW device would be the talk of the town. :)

I built the driver as a module on F15 and loaded it on my AF12, and 
found it in /proc/asound/cards, and tried to start jack on it and it 
failed to start for duplex, capture, or playback, just FYI.

You should've searched ffado-devel and linux1394-devel.

In theory, this should have worked.  What exactly does "failed" mean?

There is not PCM device for the AF12.

In theory, it shouldn't be possible for the driver to attach to the
device without having created the PCM device.  Are you sure that you
have the latest version of the driver?  Where exactly did you get it
from?  Please check that the fireworks.c file has 2275 lines, like this
one:

Re: ALSA Fireworks driver

[Doug McLain]

Aha! I had an older version that someone from the ffado list pointed me 
to.  I grabbed the .c and .h file from your link and built them (after 
defining CSR_IPCR and CSR_OPCR locally, my kernel-dev pkg doesnt have 
them) and now jack starts and I can record and play from ardour, but 
only at 44.1Khz, even though I start jackd with -r48000.  It looks like 
44.1Khz is the default setting the AF12 powers up at, and the alsa 
driver doesn't know how to change SR yet, is this the case?

I start the device up using ffado to force it into 48K, but then jack 
will no longer start using the alsa driver until I cycle power on the 
device.

The driver appears to work good in 44.1K though.  Aplay plays wav files 
using plughw, but not hw.

I also wonder if you can explain to me how to clone just that driver so 
I can keep up with it correctly using git pull.  I'm a little weak on 
git.  I just grabbed the .c and .h files manually and made my own 
Makefile for standalone module building.

Actually, the driver knows quite well how to change SR, and does this to
initialize the device to 44.1 kHz.  However, this driver was intended as
a prototype, so I didn't bother to implement making the other SRs
available to ALSA applications.

This should work if you also change FIXED_RATE_SFC (0...6 = 32/44.1/48/
88.2/96/176.4/192 kHz).

This is to be expected if your .wav doesn't have twelve channels of
32-bit samples.

The driver is in a kernel repository because it is part of the kernel;
using it with other kernel versions would require back-porting any
changes in the kernel API (as you did this with the CSR_ symbols).

Current development is in the firewire-kernel-streaming branch, where
the drivers are composed of more files and depend on some changes in
the core kernel.  There is no easy way of using these with another
kernel.

Nice, now I have it up and running with my preferred SR of 48Khz, and it 
seems to be stable.  I figured out the git stuff since the last email I 
sent.  I didn't know how to browse and switch to various branches, so I 
kept getting the wrong files in sound/firewire.

Thanks for the help,
Doug

Re: ALSA Fireworks driver

[Doug McLain]

FYI I tried #define FIXED_RATE 48000 just to see if I could use the 
driver at 48K for soem recording sessions today.  It built, loaded, and 
successfully changed the device to 48K, and jack starts fine, but no 
audio makes it from ardour to the device.  Also, aplay fails:

aplay -D plughw:AudioFire12 wg.wav
aplay: main:660: audio open error: Input/output error

Everything goes back to normal when I change the source back to 44100.
