Right, I have both the .71 and .72 prerelease versions working on demudi. Also which version of demudi?

Re: [linux-audio-user] realtime lsm module and kernel 2.6.11 on Debian

by David Baron

There are two packages: The sources and a script to use the module. As you found out, you must manualy move/copy it to ..../kernel/security/ The script is executed on startup and gives the privileges to the audio group 29.

Or try the latest version of demudi, I've been having a great time with that, the only thing that's broken in the latest version for me is Muse, but terminatorX has the lsm stuff compiled in and works fine, so I'm not sure why Muse is complaining, but hopefully that will get fixed as well.

[linux-audio-user] rlimits patch crashes audacity

by Ruben Jenster

Hi, I finally got the rlimits patch working here. Thanks to Jack O'Quin who helped me. I idiot have just forgotten to apply the pam patch. But soon after having this little success I had to determine that audacity is not working with the rlimits patch. I can start audacity but as soon as I press the record or play button audacity chrashes. (Do not wonder but I usually start audacity with 'LC_ALL=en_US audacity' because I have a UTF-8 locale and amarok would chrash with this) > LC_ALL=en_US audacity > > (audacity:19169): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() > PaHost_WatchDogProc: cannot set watch dog priority! > PaHost_WatchDogProc: killing hung audio thread! > Getötet With the same kernel (2.6.11.8) without the rlimits patch audacity works fine.

[linux-audio-user] Have a look at the kcsm .ogg stream

by M P Smoak

I've been listening to kcsm recently using alsaplayer. They have a 128k stream and a 64k mp3 stream. Both have sounded real good everytime till now. Right now the ogg stream is very distorted/corrupted. I sent them an email, but I'm still interested in what's causing this. I can bring up 2 instances of Alsaplayer and listen to first one stream and then the other. Alsaplayer reports the mp3 stream as 64k, but the streaming rate for the 128k stream varies, 110 to 230 rapidly. I never payed attention to the stream rate before but I know I've been using the ogg stream and I think I would have noticed this rapid variation. I running a recent PlanetCCRMA RH9 setup. Who's problem is it; theirs or Alsaplayers? Marv

I have to agree. If you don't want to spend the bucks for the RME then the 1010 (or 1010LT if you don't mind internal AD/DA) would be my recommendation. Jan

[linux-audio-user] 8ins/8outs (analog) plus MIDI Audio card ?

by nixobeee

Hello, I already own two Sekd cards (old ARC88) wich are neither ALSA supported, nor OSS. But I'd like to switch my audio station to Linux. Sorry if the question has been answered before, but I just wanted to know what linux-supported card would you recommend, for the same field of application (multi analog ins and outs, plus MIDI and sync). For information, I'm going to use Ardour, mainly for direct recording of my band live sessions. Thanx :) NiXO.

[linux-audio-user] keybindings in ardour

by Noah Roberts

I used ardour -b to get a printout of keybindings but it doesn't say what key does what. I think those are a list of available bindings. How do I find out what key is set for which binding and how do I set those bindings?
