[linux-audio-dev] X Error: BadWindow errors with qjackctl 0.2.15a

by Lee Revell

Every time I start qjackctl from a remote X session I get these errors at startup. I am using the Cygwin X server. X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 Minor opcode: 0 Resource id: 0x3a X Error: BadAtom (invalid Atom parameter) 5 Major opcode: 18 Minor opcode: 0 Resource id: 0x134 X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 7 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 7 Minor opcode: 0 Resource id: 0x3a Then if I activate the Messages window and move the mouse back and forth between it and the qjackctl window I get tons of these. They seem to be associated with the tooltips popping up in the main qjackctl window. X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a X Error: BadWindow (invalid Window parameter) 3 Major opcode: 38 Minor opcode: 0 Resource id: 0x3a The latter are especially annoying as they spam the Messages window not the xterm I launched qjackctl from.

Can you log in to the remote system using ssh -Y? This looks like one of the X11Forwarding problems.

[linux-audio-dev] LAC 2005 streaming: CfP

by Joern Nettingsmeier

hello everyone ! the linux audio conference 2005 @ zkm (http://lac.zkm.de) is drawing near, and it's time to get the streaming network up and running again. like last year, the idea is to stream all the lectures and discussions live over the net, and to provide webcams with either stills every 30 secs or (if we can pull it off) theora video streaming. of course we will also provide IRC channels for online participation. currently, i'm looking for people who are willing to host a streaming relay server based on icecast2. for our primary relays, we will need servers with >= 10 mbits of bandwidth (smaller links would put too much load on the master server), however, folks with less bandwidth are welcome to join in as well, but they will have to pull their streams off a secondary server. if you can donate some time and bandwidth and want to have fun with live streaming, please holler now. please also indicate whether you would be willing to participate in a sort of "stand-by streaming network" that could easily reactivated for other linux-audio-related events (i'm cc:ing tim hall who is putting together a conference in the uk later this year, and maybe conrad could use it too for the linux audio miniconf in australia...) also on the cc: list are some of the folks who participated last year (hi marco, patrice and fred!), in the hope that they will be able to join us again... we will prepare detailed instructions on how to build and configure icecast2 - previous streaming experience is not necessary, although it helps if you know your way around basic networking issues. if you are interested, please reply to my private address only, so that we don't clutter people's inboxes too much. then i'll put together an ad-hoc cc: list or maybe we'll ask for a proper mailing list on the zkm server, depending on how many people are interested... i don't have francois dechelle's current email address, perhaps someone could forward this mail to him. best regards, jörn

[linux-audio-dev] adm: list web archives have moved (was: Re: usb-asx2y on amd64 again)

Yes, we were going to announce this a bit later, but yup, it's true, the archives have been succesfully moved to their new home! :) Only thing still left to do is to update the links at linuxdj.com. > Thanks but I'm not sure that is going to help me all that > much because it looks like it specifically searches thru > the Finnish Google site... Oops, sorry about that. :) I'm used to the Finnish google.fi URL, and that slipped in by accident. The page is now fixed and submits the searches to google.com, which is probably the correct default behaviour. > Hakusi - site:lalists.stanford.edu usb-asx2y - ei vastaa yhtään sivua. > > Is there an archive around that actually indexes the > messages themselves ? Not that I'm aware of. We used to have a dedicated htdig search, but I'm not able to provide this service anymore (still a web based search, not limiting to message contents). And even if someone would offer to host the htdig service, I'm not volunteering for the job. :) Keeping the dedicated search up and running (and debugging why certain searches don't work as expected) can be a bit of a burden, so relying on google.com, search.msn.com (both of which have already crawled the whole new lalists site) and other competitors seems like a nice option to me. PS If you do put up your own archive sites, please apply some anti-spam measures to the email addresses before putting them online (and especially if you put whole mboxes online). The current mailman archives (only replacing @ with " at ") are already an easy target for address harvesters. In the current archive at lalists.stanford.edu, I've chosen to hide the tail of email addresses completely to make sure no automated script can harvest subscriber addresses. This only applies to newer messages, older ones are protected by a weaker mechanisms (similar to the default mailman obfuscation). -- http://www.eca.cx Audio software for Linux!

[linux-audio-dev] sbagen2?

by Aaron

Hi all, I am trying to create a mix from a non jack application sbagen with a bunch of mp3's. My son who is ADD has some songs he really loves, which I have mp3s of. I created a script file for sbagen to produce binaural beats but now I would like to create a mix. songs in one track the binaural beats in another. I tried sox and ecasound but sox didn't like being piped from standard out. I couldn't figure out ecasound but I would love to use ardour or rezound if possible. how do I go about feeding the output of sbagen to a recording application (what application should I use for this) I don't need a fancy mix because it is for my special education child and he won't care about quality. I do need a way to bring this about. Thanks Aaron

[linux-audio-dev] realtime-lsm in Andrew Morton's latest kernel patchset

by Jack O'Quin

Those of you who enjoy working with bleeding-edge kernels, please try Andrew's latest 2.6.11-rc3-mm2 patchset. I am hopeful that this may be included in the base kernel, soon. It would help for some of you to build this kernel, run it and report on any problems (or successes) with the realtime LSM. This version no longer supports the `allcaps' option (too much risk), so you need to run `jackd' rather than `jackstart' with it, unless you have a very recent version of JACK. (Even so, using `jackd' is preferable.) You'll need the 2.6.10 sources from <http://kernel.org/>, then the 2.6.11-rc3 patchset, followed by 2.6.11-rc3-mm2 (in that order). Configure the realtime-lsm under `security'. It can either be built-in or loaded as a module (y or m). When the module is active, its parameters can now be changed dynamically via sysfs like this... # echo 1 > /sys/module/realtime/parameters/any # echo 29 > /sys/module/realtime/parameters/gid # echo 1 > /sys/module/realtime/parameters/mlock If you try it, please let me know how well it works. -- joq

[linux-audio-dev] Change midi device order?

by airplays55＠yahoo.com

Is there a way for me to re-order the OSS (not alsa) midi devices that show up from sndstat? The reason is I am using the SB-live! soundcard and am unable to record input in rosegarden21 because it records midi from the first device (#0) and I am having somehow some kind of conflict resulting from 2 midi devices. Sndstat says: MIDI devices: 0: Error: No such device or address /dev/midi00 : Device or resource busy 1: EMU10K1 MIDI I don't know why one soundcard results in 2 drivers but I'd like to disable the bad device or reorder them. This is for knoppix (ALSA isn't an option) and and I have confirmed that midi output works (since playmidi -e works) and that midi input works (by running a short program that echo midi input to screen, using /dev/midi) __________________________________________________ Do You Yahoo!?
