Were you able to resolve this? The problem appears to be in freeglut, the implementation of GLUT installed on your system. You may need to update your display drivers or GLUT/GL libraries. Here at the sound lab, we've been able to run things well under our old RH9 boxes with PlanetCCRMA - though we did get and installed the most recent NVIDIA drivers that goes along the graphics card. Are you able to run other OpenGL/GLUT applications on your system? I don't know if this helps, but I'd be happy to work with ya to figure things out as always. Best, Ge!

[linux-audio-user] Ardour and RAM

by Drucer Ninetynine

Hi, Could somebody please clarify can Ardour and other Linux audio apps use RAM efficiently? What I mean by this question is - let's imagine I have 4GB of RAM - are these applications aware that "oh I see, there's a lot of RAM available, let's use it" and use RAM instead of immediately writing to disk which is slow and can cause latency issues? __________________________________________________ Do You Yahoo!?

[linux-audio-user] Interesting Linux audio software (ReBirth clone?)

Hi, Anyone tried this interesting looking Linux audio software? It looks like it's ReBirth clone or something. Never heard of it before although I've been watching Linux audio discussions closely. http://linux1.no/forum/viewtopic.php?t=1684 __________________________________________________ Do You Yahoo!?

It have a few bugs and it is not maintened upstream anymore. If you look at the alsaplayer devel email list, one of the last message (2006-05-28) was from a debian guy that send patches to correct some bugs and they don't even made the change in the cvs. Those patches are incorporated in the debian version, so they must be safe and well tested. Maybe at we can incorporate those fixes in our ebuild. What is silly is at the first place at a so good program is not maintened. Dominique

[linux-audio-user] 64-bit AMD dual core mobo recommendations ?

by lanas

Folks, First of all, I always appreciate reading the comments and replies to the questions. They are very useful. Recently there was a thread about a AMD64 setup but there was no clear mention of specific mobos that Simply Works. So I'd like to have recommendations from folks who actually are running successfully an AMD dual-core processor. I presently have a MSI K8N Neo4 SLI mobo and it's certainly not working well. I sent it also to California during the MSI recall for the dual-core update. Didn't change much: - USB does not work - Audio is only stereo (although it annouces 7.1 - not very encouraging) - SuSE 10.0 (and 9.3) gets confused about the two ethernet ports I have to fix them manually. - SATA Raid support is software-based (even though it has two different HW interfaces) - Audacity sometimes says it can't play any audio (could be an OS thing) Firewire works, as well as everything else ;-) So I use it, and I like the speed, especially with the 4 GB of RAM. I have a Zalman fan, and, very quiet power supply, amd quiet case fans, so it's not too bad. But I would like to get a mobo with which everything works and on which it is possible to expand (eg. adding a M Audio card for instance) with problems. Hardware SATA raid would be a plus, but I can live with SW raid. Anyone out there effectively using an AMD dual-core CPU with a 64-bit mainboard for MIDI sequencing and audio recording purposes without having to fiddle around a good percentage of the time ? If so, I'd like to get the exact mobo description and I'll do everything to get one exactly like that. Please also tell which distro is used. Thanks ! Al

[linux-audio-user] Mplayerplugin. Can it use Alsa?

by Nigel Henry

I lam listening to RTL radio.fr. It uses Realplayer for previous (listen again) transmissions, but uses WMP for live audio streams. I gave up on trying to get any version of WMP working under Wine, but Mplayerplugin is working ok, but appears to be using OSS, as does RealPlayer. Mplayer is setup to use Alsa, but Mplayerplugin's /etc/mplayerplugin.conf indicates defaults for aRts, esd, and oss. Does anyone know if it actually is supposed to work with Alsa. I tried adding Alsa "ao=alsa" , but then Firefox connecting to the RTL site, and clicking the "listen live" button resulted in some buffering, but then it just stopped (no more traffic), which seems to indicate that Alsa is a no-go with Mplayerplugin. I use aoss with Opera to listen to bbc.co.uk/radio4, using the RealPlayer plugin, but there is some crackling on top of the speech when using aoss, but I can use Gaim at the same time, and receive Gaim's sounds. Soundcard is Ensoniq PCI (ens1371 driver) (No hardware mixing) Although I can't use other music apps at the same time, I must say that the Mplayerplugin using "mplayerplug-in-wmp.so" works really well with RTL radio.fr, listening to live music. I've had no audio dropouts like I get with the BBC using realplayers nphelix.so. Any suggestions with the Mplayerplugin, and Alsa problem welcome. Nigel.

[linux-audio-user] Recommended soundcard similar to ESI juli@

by Gerhard Gaußling

Hello, I use a crappy nforce audio onboard sound. With that I'm not able to get low latencies (I'm now at 180 ms, and still get xruns, delay exceeds and some times x-server nvidia-glx (?) crashes, although I applied Ingo Molnars patch for complete rt capabilities on amd64 dapper). Now I want to get a new audio card with harddisk recording, midi, and midi capabilities and DA/Spdif. I had a look on the ESI Juli@, M-Audio Audiophile 2496, EMU 1212M, and I would prefer the Juli@, but I don't know how good is the card support in alsa. I read the changelog of 2.6.12-rc1 by Jaroslav Kysela <perex<at>suse.cz> http://kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.12-rc1 <perex<at>use.cz> [ALSA] Added ICE1724 - ESI Juli@ code (not complete) + AK4114 code + AK4358 Serial BUS drivers,AK4114 receiver,AK4XXX AD/DA converters ICE1712 driver,ICE1724 driver Initial incomplete driver for ESI Juli@ cardcards based on ICE1724, AK4114, AK4358 and AK5385. The ICE1724 and ICE1712 main files plus some drivers are also updated (cleanups and new callbacks). Signed-off-by: Jaroslav Kysela <perex<at>suse.cz> I also read some messages, that the Juli@ is not very good supported yet. Does somebody have experience with that card, or can somebody suggest an other card for medium hobbyist/semi-pro requirements? Kind regards Gerhard Gaußling
