[linux-audio-user] Jack problem in Brazil

by Alexander

Hi! I'm brazilian and I don't speak english. So... please... be patience :) I have install jack 0.80 in one notebook Compaq presario 1200 with sound-card snd-via-82xxx(this module is from Alsa-Project). All songs in my coputer play with no problems. But when I try start jackd the system showme this error: JACK compiled with System V SHM support loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|nomon|swmeter|rt jackd: pcm.c:689: snd_pcm_nonblock: Assertion 'pcm' failed. received signal 6 during shutdown (ignored) I create all of directories of README. And I put in fstab the lines: none /mnt/ramfs tmpfs defaults 0 0 shmfs /dev/shm shm defaults 0 0 My kernel support shm and i can mount manually this directories. I do this because before my last installation(compile) I use --enable-posix-shm But in this time I remove all jack files os my system and killall -9 all process of jackd and recompile with stadard options. The error is the same(but change the first line "with POSIX ..." for "with System V..."). Is OK. So... my jack is compile with NO errors and the module of my sound card is ok. The process of arts, esd, nas, etc, NOT exist in my process list(I use WindowMaker). I have the directories(mounted) /mnt/ramfs and /dev/shm. I don't have any sound aplications started(no one). But I get the same error. I create the /tmp/jack with permissions 777. When i start jackd this directory is removed!!!! What's this error? Somebody have some idea what is this? I speak to Patrick Shirkey and I get much help, but my problem seems to be in my system. Any help? Thanks a lot! Alexander Brazil - Rio de Janeiro

[linux-audio-user] Recording from Line-In

by G Cote

I'm having problems recording from line in. Without knowing exactly what's going wrong, all I can say is that I can only playback "silence." As I'm recording, I can hear the audio being fed back through the external speakers. I can also use various mixers to mute/unmute and set the volume on the "Line" setting. So I'm pretty sure everything is hooked up right. I initially tried using sox/notlame/mpg123 ... # record and encode $ sox -t ossdsp -w -r 44100 /dev/dsp -t cdr - | notlame -k -v -S - /tmp/out.mp3 # playback $ mpg123 /tmp/out.mp3 I've since tried to simplify things ... $ rec -d /dev/dsp /tmp/out.wav $ play /tmp/out.wav Neither of them work. System details are provided below. What else can I do to troubleshoot this? Thank in advance - gary System . redhat 8.0 (2.4.20-19.7) . alsa-0.9.6 .

[linux-audio-user] question about cue sheet apps

by Dave Phillips

Greetings: While profiling FLAC I discovered that the format includes a metadata format for including cue sheet data for use in CD mastering applications. When I looked for a Linux-based cue sheet editor I found only the very outdated CDB (CD Builder), which, true to its author's advice, will not build under GTK 1.2 or 2.x. I thought perhaps JAM would concern itself with cue sheet data but I think that's not its domain (the FLAC docs note that the cue sheet data is intended for CD authoring apps). Btw, I downloaded and tried running some Windows-based cue sheet editors under WINE, with varying success, but none were completely useful. Maybe I should update my WINE installation again, but I'd prefer a Linux-based solution anyway. Sorry for the cross-post, I thought perhaps someone on LAD might be developing such a creature (?). Do any users on LAU utilize a cue sheet editor for any of their work ? Best regards, == dp

[linux-audio-user] RAR archives

by Larry Troxler

How is everyone extracting RAR archives? I tried using a shareware linux rar RPM, with the rar executable dated March 2001, but it fails on the base drum kit sound font from www.nskit.com , which the message "Unknown method in ..." for each of the component files. Is there a newer linux rar available somewhere, or is it recommended instead to use winrar in wine? Larry

RE: [linux-audio-user] Jack problem

by Vescovi Christophe

Hi all, Back at home I have done some experiments (Sorry for the long post !!) Since I was using qjackctl to launch jack I did not notice that the error message "cannot lock down memory for RT thread (Operation not permitted)" was not a jackd message but a message from qjackctl when it try to connect to the jack server. As root everything work fine. When running jackstart as normal user I get : --cut here-- [christophe@localhost christophe]$ jackstart -R -v -d alsa -d hw:0 -p 1024 back from read, ret = 1 errno == Success jackd 0.80.0 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 3701 waiting for signals JACK compiled with System V SHM support capabilities: =i cap_setpcap,cap_ipc_lock,cap_sys_nice,cap_sys_resource+ep loading driver .. new client: alsa_pcm, id = 1 type 1 @ 0x805ac70 fd = -1 creating alsa driver ... hw:0|hw:0|1024|2|48000|nomon|swmeter|rt open registered port alsa_pcm:capture_1, offset = 4096 registered port alsa_pcm:capture_2, offset = 8192 registered port alsa_pcm:playback_1, offset = 0 registered port alsa_pcm:playback_2, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() starting engine load = 0.0586 max usecs: 25.000, spare = 21308.000 load = 0.0715 max usecs: 18.000, spare = 21315.000 load = 0.0850 max usecs: 21.000, spare = 21312.000 --cut here-- So it seems ok, capabilities are enable,I start ams synth with "ams --jack" still ok but when I try to connect ams_synth to alsa : --cut here-- [christophe@localhost christophe]$ jack_connect ams_128_0:Out_ID1_0 alsa_pcm:playback_1 engine sample rate: 48000 cannot lock down memory for RT thread (Operation not permitted) cannot activate client --cut here-- The output of the jack terminal during the connection is : -- cut here -- registered port ams_128_0:Out_ID1_0, offset = 12288 registered port ams_128_0:Out_ID1_1, offset = 16384 new client: jack_connect, id = 4 type 2 @ 0x411ff000 fd = 14 removing failed client jack_connect state = Not triggered errors = 0 adios senor jack_connect *&*&*&*&** senor jack_connect - you are a ZOMBIE ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() -- cut here -- my /etc/fstab is -- cut here -- /dev/hda6 / ext3 defaults 1 1 none /dev/pts devpts mode=0620 0 0 /dev/hda9 /home ext3 defaults 1 2 none /mnt/cdrom supermount dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-15,codepage=850,umask=0 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=auto,--,iocharset=iso8859-15,sync,codepage=850,umask=0 0 0 /dev/hda1 /mnt/win_c vfat iocharset=iso8859-15,codepage=850,umask=0 0 0 /dev/hda5 /mnt/win_d vfat iocharset=iso8859-15,codepage=850,umask=0 0 0 none /proc proc defaults 0 0 /dev/hda8 /usr ext3 defaults 1 2 /dev/hda7 swap swap defaults 0 0 shmfs /dev/shm shm defaults 0 0 none /mnt/ramfs tmpfs defaults 0 0 none /tmp/jack tmpfs defaults 0 0 -- cut here -- If it work as root it should not be a problem of memory !!

I wanted to use the wavetable synth, even if it was of lower sound quality, as a tool to listen to work in progress so as to reduce the load on the processor. I have been having some problems with crackling noises which I assume are caused by MusE and or the softsynth overloading the processor when playing back a multitrack midi file. Today I did some experimenting with TiMidity as the softsynth for MusE -- I got it configured with timidity -iA in one terminal and muse -R in another. Then in the midiport configuration it popped up with timidity port 0 for the first midi port. Unfortunately this produced no sounds on testing. I opened the track info number and tried to select a preset, but all that it had was "???" -- no patches to select from. Is there another switch that needs to be thrown to load sounds into TiMidity? Something else? I am running the Planet CCRMA acpi kernel, RH 8.0, with TiMidity++ 2.11.3-4.1, TiMidity midia instruments 2.11.3-4.1, and eawpats 12-1 installed. Thanks, Barton
