-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello folks, I recently have taken the effort installing ffado from SVN on Ubuntu Studio. My Presonus works quite OKayish with freeBoB but I cannot set the sync to external via S/PDIF - unfortunately it looks, like ffado does not offer any method to set this either. As I try to start the ffadomixer it says, my device is not supported :-( Any hints? And: does any body know, what devices are supported by ffadomixer ? best regards -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHsLtJ1Aecwva1SWMRAkzcAJ9TyInerT3X9l2Zuj2NUdE9tt/HxwCfUdtV cfuDvmDUoL925Sy0ba/Iz4U= =uUlY -----END PGP SIGNATURE-----

[LAU] LAC 2008: bandwidth to burn and volunteers needed

by Eric Dantan Rzewnicki

LAC 2008: bandwidth to burn and volunteers needed The 6th annual Linux Audio Conference is taking place in Cologne, Germany, Feb 28th to March 2nd, 2008. As with each previous year this year's conference will be streamed live over the internet in ogg theora via icecast. The stream server is up at: http://lac2008.khm.de:8000/ There is nothing to see at the moment, but keep checking over the coming days as we hope to have a test stream up soon. This year we are in the unique situation of having a Gigabit link donated by CITIZENMEDIA: http://www.ist-citizenmedia.org/ They have asked us to use up as much of their bandwidth as we can so they can see how well the link performs. This year the core team, Joern Nettingsmeier and myself, are recruiting volunteers to spread the workload. To that end we have set up a mailing list and irc channel to coordinate our efforts. We will also have a wiki shortly. If you will be coming to Cologne for the conference please consider signing up to help. If you are not coming, please enjoy the fruits of our labors by watching the streams and participating via irc. stream team mailing list: http://zhevny.com/mailman/listinfo/lac-streams general conference chat: #lac2008 on irc.freenode.net stream team tech talk: #lac2008-tech on irc.freenode.net Thanks, Eric Rz. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[LAU] Device numbering

by Peter Plessas

Dear List, having strange Problems with the numbering of devices in /proc/asound/cards. The computer has a built-in RME9652 and two usb-Midi-Interfaces. I have specified the order in the /etc/modules file as follows: snd_rme9652 index 0 snd_usb_audio index 1,2 although from time to time, when unplugging and plugging in the usb-Midi-interfaces, they get inserted as devices 0 and 1, thus shifting the RME card to position 2 which causes great confusion. This setup is to be used for an important performance, so it is absolutely crucial to get this sorted out, and i hope for great hints and suggestions as usual from this wonderful list. with regards, Peter

[LAU] Converting OpenSuse 10.3 to JAD

by Christian Delahousse

Hey guys, I just recently posted here stating I was looking to convert my laptop for a live performance machine using linux and mostly Pd (I was thinking pd, but I said Max MSP instead). After browsing around for various distros, I chose JAD become it was the most recently updated one, was advertised to have a realtime kernel and could run with ASIO drivers. The problem was that I couldn't install it from the disk since my DVD drive is semi kaput and can really only read CDs. So instead, I opted to install openSuse 10.3 instead because they offered to install it via a net connection. Its up and running (aside from my flipping wireless! BROADCOM!!!) and I want to start some wireless work by converting it into a JAD type workstation. The problem is that JAD is based on OpenSuse10.2 and I'm running 10.3, which has me concerned. There is a guide (http://wiki.jacklab.net/index.php/3_Steps_to_JAD_for_Beginners) on how to convert Suse10.2 to jad, but I'm afraid of compatibility issues since my version is 10.3 and I don't know if the techniques described there transfer over. Furthermore, I snooped around the Jacklab repository and found a OpenSuse 10.3 folder, but as soon as I added it, I got a warning from YaST telling me the description file was broken... or something. Furthermore, is there a way to install all the audio packages at once instead of downloading them individually. Thanks -Chris

Re: [LAU] Clics and pops

by Sampo Savolainen

Hi, Are you sure the clics and/or pops are in the source material? Your previous problem hints that your jack setup might not be optimal and the problems could come from jackd xruns. If the problem is with the source material, you could try gnome wave cleaner: http://gwc.sourceforge.net/ Sampo Quoting Nicolas Peltier <peltier.nicolas(a)gmail.com>: > Hello, > > you may recognize my name : i'm one of the linuxaudio users who yelled > about > watchdog timeout (jack problem). > it still doesn't work and i'm still interested in any advice... > > BUT my mail isn't about that problem.

[LAU] Clics and pops

by Nicolas Peltier

Hello, you may recognize my name : i'm one of the linuxaudio users who yelled about watchdog timeout (jack problem). it still doesn't work and i'm still interested in any advice... BUT my mail isn't about that problem. I couldn't record and playback simultaneously so i tried another solution : recording through my Micro BR and then use ardour to playback and mix the audio files. The only problem that remains is i have clics or pops (i dont know the difference) on my guitar record...i tried to suppress them with audacity, but it seems not to work (with me as a user). Could i have explanations about using that function? Is there a more efficient/ easier tool to do that? why do clics and pops exist (it's a wav file)?

[LAU] OT: 32-bit vs 64-bit speeds

by david

Just curious, but I've heard that 64-bit OSes are slower than 32-bit ones. That seems odd to me. Any truth to it? -- David gnome(a)hawaii.rr.com authenticity, honesty, community

[LAU] [ANN] Aqualung 0.9beta9.1 released

by Tom Szilagyi

The Aqualung development team is pleased to announce the latest release of the Aqualung music player. Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, today also running on FreeBSD, OpenBSD and Microsoft Windows. It plays audio CDs, internet radio streams and podcasts as well as soundfiles in just about any audio format and has the feature of inserting no gaps between adjacent tracks. The ChangeLog is included below. Please note that our website has moved to http://aqualung.factorial.hu Please update your links and bookmarks. Enjoy, Tom 2008-02-10 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta9.1 http://aqualung.factorial.hu This is a bugfix, stability and performance oriented release also containing a few updates to existing functionality. By using this version, your Aqualung will be more stable, and in some cases significantly faster. All users are encouraged to upgrade. The project homepage has moved to http://aqualung.factorial.hu Please upgrade your pointers and bookmarks. Notable changes: * Playlist code refactoring for improved performance. Please note that incompatible changes have been made to the playlist format: this means that your old playlists won't be parsed, you'll have to re-create them. (NOTE: Music Store contents are unaffected. If we ever change the Music Store format in a backward-incompatible way, we will provide tools to migrate your precious store data.) * Fix threading problems that caused random crashes for some users. * Fix lurking bug that sometimes resulted in getting stuck at the beginning of a track when Sinc interpolator sample rate converters were used. * Modified the way of opening ALSA output to achieve non-exclusive driver access. * New, more versatile title string generating templates. Make sure to check the documentation. * Added option to periodically save playlist. * Several fixes concerning command line file and playlist loading, esp. with the -L flag. * Better metadata handling for external files in playlist. * Increment CDDB revision number on resubmitting an existing disc. This is essential for correcting existing CDDB entries, otherwise the CDDB server rejects the submission. The latest CVS version from http://libcddb.sf.net is required for this to work (Aqualung-Win32 is built with this version). * OpenBSD-related portability fixes. Aqualung should now compile cleanly and be fully functional OOTB on OpenBSD 4.2. * Updated German, Hungarian and Italian translations. Added Russian translation.
