Hi, I'm having trouble with Jack on a Dell D420 laptop. Sound is configured and plays fine but when I start jack I get regular xruns and then it crashes after about 30 seconds. If I start and audio app, I can see it appear in the connections, but no sound plays and then when jackd goes down, it complains about a broken pipe. I'm totally stumped. Its not a problem with the frames/period as I've tried all different combos (up to 1024 frames/period with 8 periods per buffer) All that is displayed in Any ideas? lspci reports: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) lsmod reports: snd_rtctimer 4640 1 snd_hda_intel 346136 3 snd_pcm_oss 42400 0 snd_mixer_oss 18048 1 snd_pcm_oss snd_pcm 78852 2 snd_hda_intel,snd_pcm_oss snd_page_alloc 11400 2 snd_hda_intel,snd_pcm snd_hwdep 10628 1 snd_hda_intel snd_seq_dummy 4868 0 snd_seq_oss 35968 0 snd_seq_midi 9376 0 snd_rawmidi 25632 1 snd_seq_midi snd_seq_midi_event 8576 2 snd_seq_oss,snd_seq_midi snd_seq 54992 10 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 24836 3 snd_rtctimer,snd_pcm,snd_seq snd_seq_device 9612 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 57636 20 snd_rtctimer,snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_hwdep,snd_seq_dummy,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 9312 1 snd /usr/bin/jackd -v -R -p1024 -t5000 -dalsa -dhw:0 -r44100 -p1024 -n8 gives: getting driver descriptor from /usr/lib/jack/jack_freebob.so getting driver descriptor from /usr/lib/jack/jack_oss.so getting driver descriptor from /usr/lib/jack/jack_alsa.so getting driver descriptor from /usr/lib/jack/jack_dummy.so jackd 0.109.2 Copyright 2001-2005 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 JACK compiled with System V SHM support. server `default' registered registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via clock_gettime loading driver .. new client: alsa_pcm, id = 1 type 1 @ 0x805a4c0 fd = -1 apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|8|44100|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames (23.2 ms), buffer = 8 periods ALSA: final selected sample format for capture: 32bit little-endian ALSA: use 8 periods for capture ALSA: final selected sample format for playback: 32bit little-endian ALSA: use 8 periods for playback new buffer size 1024 registered port system:capture_1, offset = 4096 registered port system:capture_2, offset = 8192 registered port system:playback_1, offset = 0 registered port system:playback_2, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() 7314 waiting for signals new client: alsa-jack.jackP.7319.0, id = 2 type 2 @ 0xb7edd000 fd = 10 registered port alsa-jack.jackP.7319.0:out_000, offset = 12288 registered port alsa-jack.jackP.7319.0:out_001, offset = 16384 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() connect alsa-jack.jackP.7319.0:out_000 and system:playback_1 (output) ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() connect alsa-jack.jackP.7319.0:out_001 and system:playback_2 (output) ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() jackd watchdog: timeout - killing jackd Thanks Steven -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
