[SOLVED+PATCH] Beagleboard running Jack Audio Connection Kit

Normally jackd fails to run on the Beagleboard Angstrom distro when
audio capture is enabled. Jackd can be made to run if given the right
arguments.

# jackd -d alsa -p 256 -n 4 -P hw:0 -C hw:0 -S -r 48000

Important settings seem to be -p 256 -n 4.

Tested on Rev C4 with jack-server_0.118.0-r0.5_armv7a.ipk .

I have a patch which makes these working values the default for jackd
in angstrom. Who can review and commit it?

Great work.

I guess Koen is reading your message anyway. But normally you should
send patches for Ȧngström to developer list [1].

Thanks,

Thanks for the pointer.

BTW I was also able to get Jack started under Ubuntu 10.04 lucid using
these parameters.

Thanks!

Best,

I'm running jackmp, jack_lsp just hangs there - Ubuntu on a C3.
Slightly off-topic I can't get anything recorded from the Mic, neither on Ubuntu nor on Angstrom narcissus. It seems to record a wav file OK, but on playback I just get white noise.

I am using jackmp as I especially need jack_connect, no problems on openSUSE 11.3 or Kubuntu 10.04 LTS x86_64 boxes.
