Hello everyone, Jackbeat version 0.7.6 has just been released. This is a bugfix release. Homepage: http://jackbeat.samalyse.org Download: http://jackbeat.samalyse.org/downloads/jackbeat-0.7.6.tar.gz News ~~~~ - An issue which prevented Jackbeat to compile on recent 64bit Linux systems has been fixed. This affected Fedora 13, Ubuntu 10.10, Arch Linux and possibly others. - Jackbeat doesn't try and connect to PulseAudio by default anymore, since this may hang on certain systems. The PulseAudio output driver must be explicitly selected in the preferences. ChangeLog ~~~~~~~~~ jackbeat (0.7.6) * #61: fix compiling on recent x86_64 Linux systems such as Fedora 13 * do not try and connect to PulseAudio by default, it may deadlock Have fun -- Olivier

No ALSA after installing stock Debian kernel

by David Baron

No cards, no /proc/asound, nada Here is a part of the problem: $ dmesg | grep -i snd [ 5.501289] snd: Unknown parameter `device_mode' [ 5.521068] snd: Unknown parameter `device_mode' [ 5.548879] snd_timer: Unknown symbol snd_info_register [ 5.549233] snd_timer: Unknown symbol snd_info_create_module_entry [ 5.549514] snd_timer: Unknown symbol snd_info_free_entry [ 5.549995] snd_timer: Unknown symbol snd_iprintf [ 5.550369] snd_timer: Unknown symbol snd_ecards_limit [ 5.550684] snd_timer: Unknown symbol snd_oss_info_register [ 5.551992] snd_timer: Unknown symbol snd_unregister_device [ 5.552298] snd_timer: Unknown symbol snd_device_new [ 5.552789] snd_timer: Unknown symbol snd_register_device_for_dev [ 5.555342] snd_timer: Unknown symbol snd_info_register [ 5.555677] snd_timer: Unknown symbol snd_info_create_module_entry [ 5.556022] snd_timer: Unknown symbol snd_info_free_entry [ 5.556537] snd_timer: Unknown symbol snd_iprintf [ 5.556921] snd_timer: Unknown symbol snd_ecards_limit [ 5.557275] snd_timer: Unknown symbol snd_oss_info_register [ 5.557529] snd_timer: Unknown symbol snd_unregister_device [ 5.557852] snd_timer: Unknown symbol snd_device_new [ 5.558402] snd_timer: Unknown symbol snd_register_device_for_dev [ 8.488754] snd: Unknown parameter `device_mode' [ 8.520580] snd_seq_device: Unknown symbol snd_info_register [ 8.521128] snd_seq_device: Unknown symbol snd_info_create_module_entry [ 8.521679] snd_seq_device: Unknown symbol snd_info_free_entry [ 8.522232] snd_seq_device: Unknown symbol snd_seq_root [ 8.522793] snd_seq_device: Unknown symbol snd_iprintf [ 8.523669] snd_seq_device: Unknown symbol snd_device_new [ 94.168026] snd: Unknown parameter `device_mode' [ 94.177591] snd_seq_device: Unknown symbol snd_info_register [ 94.177807] snd_seq_device: Unknown symbol snd_info_create_module_entry [ 94.178028] snd_seq_device: Unknown symbol snd_info_free_entry [ 94.178255] snd_seq_device: Unknown symbol snd_seq_root [ 94.178513] snd_seq_device: Unknown symbol snd_iprintf [ 94.178878] snd_seq_device: Unknown symbol snd_device_new I had compiled some of this stuff into custom kernels to solve the previous outbreak. Seems I should not need to do this and stock linux-images should work. Anyone had this and fixed it?

[ANN] QmidiCtl, QmidiNet 0.1.0 Out Now!

by Rui Nuno Capela

Howdy! It's been a long summer hasn't it? Bad news is that laudable 'spring cleaning' has slipped a bunch and in fact, is still on going with no end on sight, exactly as the 'uber-procrastinator' predicted! ;) Nevertheless, QmidiCtl, QmidiNet 0.1.0 are out now! This release marks the fact that QmidiCtl [1] is now made available from the official Maemo 5 repository [3]. So that you can download and install it directly from your N900 [4]. You'll find it on the Multimedia section. Second, QmidiCtl [1] is now fully configurable with regard to which MIDI events are sent and/or recognized. It's not MMC-exclusive anymore. Third, QmidiNet [2] also talks JACK-MIDI now. Although (very) experimentally. And you don't have to opt out on ALSA-MIDI. You can have both MIDI interfaces running as long as you please. Finally, Paul de Vries shows us a magnificent video re. How To: Setup QmidiCtl on The Nokia N900 with Renoise [5]. Alas, it's on Windows and using ipMIDI [8] as the gateway back-end. No sweat :) If Renoise [6] is to run on Linux he would use QmidiNet [2] or multimidicast [7]. Take note that the latter only does ALSA MIDI and doesn't handle MIDI SysEx messages as certain as MMC is. Kudos to Paul.

Help with installing/building icecast/ices2 kh branch

by Julien Claassen

Hello everyone! I'm just now trying to build the kh branch of icecast and ices. I managed to build icecast2, but now I'm in trouble. There are several libs (directories in the kh branch: net thread libshout m4 ices icecast Unfortunately some directories (net, thread) don't contain a configure script. Perhaps they are just included with the other builds? When I try to compile libshout I get this error messag: log/log.h no such file or directory. In icecast I had no timing handler, although I have gettimeofday. So I edited the sourcecode a bit. Not sure if this is the desireable way of doing it. :-) Could someone help me a bit? Some documentation on how to do it would be enough. but I didn't see any, only the svn link and the list of special features (like jack plugin for ices).

No sound from paulstretch

Input almost gone after upgrading from kernel .31 to .33?

by Arve Barsnes

Hi, I can't remember reading anything about this, so I hope you can help me out. I upgraded my RT kernel from my old trusty 2.6.31.12-rt20 that I had been using for a good while, and up to 2.6.33.7-rt29. Now, when I try to record anything in ardour, the input volume is below audible. The indicators on my sound card suggest the sound is close to clipping level, which earlier has been more than enough, and the sound is indeed coming through, since when I normalize whatever I have recorded in ardour, what I actually played shows up. Any ideas what might be causing this? Regards, Arve

OT: external sound for linux card advice

by Lorenzo

Hi all, I'm sure this has been discussed many times, so sorry for re-iterating... but I guess new drivers and products come out each day, so here you go: I'm looking at external audio cards (for use with my laptop) especially to do multichannel (balanced!) output - Obviusly they should work with linux-jack (ubuntu if there are any issues with this distro) - at least 8 balanced outputs I'm looking at these:http://www.echoaudio.com/Products/FireWire/index.php possibly in the second-hand market and because they are listed as "full support" on the ffdao site. Any other experience advice is very welcome Bests, Lorenzo.

Another aspect of a pc for audio is noise. I was wondering, might it be possible to use a long cable to my pc monitor and place my pc in another room. Will there be any degradation of the quality of the visual display with a long >= 5m. cable? Regards, \r

Re: [LAU] Audacity compressor in ardour and organising plug ins in audacity

I'm not certain where that compressor comes from. If it's an audacity built-in, then I wouldn't know if it could be used with ardour, nor how to do that. But, I suspect that it can't be used with ardour; that's just my guess. Are there any of the LADSPA compressors which suit your needs? Those could be used with both audacity and ardour. Sorry to not be much help.... -- Kevin
