[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 -M 23:05:45.300 JACK was started with PID=27006 (0x697e). jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 48000 creating alsa driver ... ews_24jack|ews_24jack|64|2|48000|0|0|hwmon|hwmeter|soft-mode|32bit configuring for 48000Hz, period = 64 frames, buffer = 2 periods 23:05:47.429 Server configuration saved to "/root/.jackdrc". 23:05:47.431 Statistics reset. 23:05:47.449 Client activated. 23:05:47.451 Audio connection change. 23:05:47.501 Audio connection graph change.
