Hi folks,
I'm having some trouble building a working asound.conf to get my soundcards
functional using jack.
The audio hardware consists of 3 Terratec ice1712 boards: 2x EWS88/D + 1x
Phase88, hooked up using the EWS connect clock synchronisation cables. My
goal is to get full duplex audio I/O for my home studio: 16 channels ADAT
in/out and 8 channels analogue in/out. I verified that this configuration
works from my old windows 2000 partition (using the terratec ASIO driver).
Till now I did not succeed getting this gear fully working in my linux
environment; it seems that I'm having trouble with the asound.conf to setup
the binding for the devices.
- running jack addressing the hw: devices directly works flawless; but that
way I can only use one card at a time
- as per descriptions from the mailing list archive I tried to setup an
aggregate device using the alsa multi type plugin. Since Jack needs to
mmap the buffer it needs an additional route type plugin to make the
capture stream interleaved. However, at this stage I run into a few
issues:
* due to the different number of ports the ice1712 has for
playback (12) and capture (10) I can't do full duplex I/O.
* when I do a capture only from the route plugin I hear a distorted
sound (quiet, metalic, you can hear the rhythm from the orignal
track), which I suspect is caused by the route plugin. I can't
verify if this effect is specific to my 64bit machine or also
present on 32bit
* I tried to setup different input/output for capture and playback
using the asym plugin type, but this attempt caused jackd to kill
the graph after a few seconds full of xruns.
If anyone has a pointer to or copy of a working asound.conf for multitrack
recording/playback using multiple ice1712 based cards I'd be very interested
to see those.
Some details about the software I'm running:
Advanced Linux Sound Architecture Driver Version 1.0.9b.
kernel 2.6.12-gentoo-r4 on AMD64 hardware
Jackd 0.99.0
Here's my non-functional attempt at a asound.conf for binding 2 Terratec

New subject: [linux-audio-dev] Re: trouble binding multiple ice1712 devices [part2]
While still trying to get my multichannel gear up & running I made some
(small) progress: I can successfully capture & playback 24 channels using my
Terratec boards.
arecord -M -v -D ews_24fd -t raw -c 24 -f S32_LE -r 48000 |
aplay -v -M -D ews_24fd -t raw -c 24 -f S32_LE -r 48000
Unfortunate I still can't get it to run using Jack because the capture
stream can only be opened using MMAP_COMPLEX access. Does anyone know how to
transform this stream into MMAP_NONINTERLEAVED (which is what jack prefers) or
in MMAP_INTERLEAVED format?
I tried an ALSA route pluging but that failed terribly: continious bursts of
xruns
arecord -M -v -D ews_24jack -t raw -c 24 -f S32_LE -r 48000 |
aplay -v -M -D ews_24jack -t raw -c 24 -f S32_LE -r 48000
and jack also hates this config:
23:05:45.278 /usr/bin/jackd -R -p256 -t10000 -dalsa -dews_24jack -r48000 -p64 -n2 -s -H
