Re: OT: Accelerated 3D GFX cards with Free drivers (was Re: [linux-audio-user] Re: The best distro for music creation)

FlightGear, for instance, is unusable on either a Matrox G400 or a G550 (unless you like 2-4 frames per second on an Athlon XP 2000+ box). Then, on top of that, in OpenGL scenes that involve lots of detailed texturing on lots of polys, both G400 and G550 users have routinely reported full system hard lockups with DMA idle timeouts (see the BTS for XF86, X.org, freedesktop.org, the DRI project, and the forums at Matrox for more). But don't bother mentioning any of the above to Matrox -- they'll simply tell you that however free their drivers may be, OpenGL is *not supported in Linux*, and any OpenGL problems you have, you're on your own. That right there is a showstopper. I bought a Matrox card *because* of the open drivers; when their response to my hard lockup problems was "we don't support OpenGL on Linux", I ended up feeling like I'd been taken. -c

[linux-audio-user] Burning CDs under 2.6?

by Paul Winkler

I haven't attempted to burn a cd in a long time, apparently not since I upgraded my kernel to 2.6 (currently 2.6.13), and hmmm, it no longer "just works." Argh. gcdmaster crashes every time I select "new audio CD". Got a message pending replies on the cdrdao-devel mailing list. Meanwhile, I thought I'd try cdrecord, which never gave me trouble before. cdrecord -scanbus complains loudly about the kernel: cdrecord: Warning: Running on Linux-2.6.13-gentoo-r5-nosmp-nopreempt-wireless cdrecord: There are unsettled issues with Linux-2.5 and newer. cdrecord: If you have unexpected problems, please try Linux-2.4 or Solaris. cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. -- Paul Winkler http://www.slinkp.com

I get a significant less number of xruns when I run the vesa driver instead of the nv driver. (No, Lee, the nvidia driver doesn't work for my built-in gfx-board and my very old xfree X. ;-) .) --

[linux-audio-user] Wine asking for feedback on Audio needs

by guy

According to wine weekly news (lhttp://www.winehq.com/?issue=301) the wine project is asking for feedback on its handling of audio. If I can quote: /Alexandre mentioned there were some new changes for better audio driver management in winecfg. That work has been done by Robert Reif and this week he asked if anyone could give him some feedback regarding the lesser used (and more broken) audio drivers:/ /Is anyone using the arts, esound or jack sound drivers for non trivial use? By non trivial, I mean more than one application or more than a single device. If so, I am interested in getting information on the software you are using and how it is using the drivers. / /Would redesigning these drivers to show up as a single device per physical device which allowed being opened more than once be a problem?/ I am sure there are people on this list who know what they are talking about ( & I exclude myself from that!) who could really speak up for the requirements for serious audio work & wine. cheers Guy -- No virus found in this outgoing message.

[linux-audio-user] Mono only from pci capture, emu10k1

by Brian Dunn

Well I've made alot of progress on my Gentoo system, and i'm actually trying to make some music with it now. I'm trying to use the aux input on my SBLive Value (the line in jack is busted) to record two things at once from my old school mixer, using it's stereo bus. I pan the keyboard to the right, and the mic to the left, and then use jack to route alsa_pcm capture chanels one and two to seperate busses in ardour. but alas, the right bus is always silent. I've checked it in M$XP with the kX drivers, just to make sure my little custom wiring job was working. I set the AC97 capture to Aux, and left and right chanels where isolated, keys on one and mic on t'uther. So the hardware is working right. Is this a alsa mixer issue, because that thing baffels me! this is probably a question for the alsa list, but i thought maybe some of you gents have had this same isue. Gratefull, brian

[linux-audio-user] Linux Sampler

by Mehmet Okonsar

What can you say about the usability of the LinuxSampler in its current state.. Giga import? Disk streaming? Writing audio to file? GUI? ------------- Best regards, Mehmet Okonşar, pianist-composer www.okonsar.com mehmet(a)okonsar.com

>From: James Stone <jmstone(a)dsl.pipex.com> > >so if you were to build a linux based synth, and sell it >with LS installed, they would like to get some money from you for it, >which they would not be able to do under the GPL. Many GPL authors have accepted that fact. It is not a shame to not get money from your software! Why would synth manufacturers have to pay? Why they are not allowed to enjoy of free software the same way as we end-users? But, some other people may finish the pure-GPL fork of LS. Then the synth manufacturers need not pay to the fake-GPL LS authors either. Damn, what a wasted time in duplicate work would that be!

[linux-audio-user] wav to spectrum-image

by Andrew Gaydenko

Hi! Is there some kind of tool to get a spectrum image for a given sound file? OK, I can start the jaaa, connect it with a player and get average after the song is finished. But it's too long to wait :-) Andrew

[linux-audio-user] How to get good vocal sound

by Bill Allen

I've been struggling with a technique problem. How do you get your vocals to sound good? I know that you can't make a silk purse from a sow's ear, but you can make the best of what you've got. What combination of plugins and settings do you use to get the best sound from vocals particularly in Ardour? I know that this is one of those subjective questions for which the best answer is try it out yourself and find what sounds best, but there are so many plugins (an embarassment of riches), each of which has many settings, that a brute force search of all the combinations would take forever - not to mention that after a while, my poor ears become exhausted with the effort and refuse to hear differences anymore. So what I'm really looking for is good starting points to work from. One combination that I like is GVerb to get depth and L/C/R Delay to get width. Even with those two getting the settings right takes time. For comunication, I've included a jack rack with some settings I've found that work OK. I would love your critiques and suggestions for other setups. Regards, Bill

[linux-audio-user] No sound from streaming audio + ALSA

by Paulo Marcel Coelho Aragao

Hi, I recently switched from OSS to ALSA and no sound comes from streaming audio. CD playing with xmms or cdplay works correctly. Streaming audio with xmms or gxine produces no sound. I can see that the server was contacted and the player is reproducing the stream, but only a hissing sound comes from the loudspeakers. I ruled out mixer problems because CD playing produces sound. I'm running Debian sid, kernel 2.6.14-2-686, on a Fujitsu E342 laptop, with onboard ES1879-chip Soundblaster-compatible soundcard. I've attached the output of the http://alsa.opensrc.org//aadebug.txt script. I'm really puzzled why CD playing produces sound but streaming audio doesn't. I googled on 'alsa streaming audio sound linux' and was surprised that nobody seemed to have bumped into this. Could anybody give me any leads on how to pursue this problem further ? Thanks for your attention, Paulo
