ATI Radeon - binary driver - with linux realtime kernel

by Emanuel Rumpf

Hi I managed to install the ati-radeon driver on my realtime-kernel driven system. ( Debian GNU/Linux, 2.6.31-rt11 ) For your information, here is how I did. I downloaded the linux driver from: http://support.amd.com/us/gpudownload/Pages/index.aspx This information applys to "ATI Radeon HD 3xxx Series" only, but other drivers might require likewise changes. Installer used: ati-driver-installer-9-10-x86.x86_64.run --------- 1. Start the installer. But don't continue. This will extract the installer-files to the current directory. 2. Open a new terminal, change to the extracted directory (called something as fglrx-install.08df92 ). 3. CHANGE THE FILE: firegl_public.c in install/lib/modules/fglrx/build_mod/firegl_public.c (and maybe: common/lib/modules/fglrx/build_mod/firegl_public.c ) AS FOLLOWS: THIS (LINE ~ 1028): for (i = 0; i < __KE_MAX_SPINLOCKS; i++) dev->spinlock[i] = SPIN_LOCK_UNLOCKED; CHANGES TO: for (i = 0; i < __KE_MAX_SPINLOCKS; i++) DEFINE_SPINLOCK( dev->spinlock[i] ); THIS (LINE ~ 5001): init_MUTEX(&(mutex_obj->mutex)); CHANGES TO: semaphore_init( &(mutex_obj->mutex) ); 4. go back to the installation terminal, continue and finish the installation. good luck. -- E.R.

LAM please!

by Garry Ogle

Another suggestion for all you talented linux-using musicians and composers: please consider making an entry on LAM http://lam.fugal.net linking to your work. ( I know some of you do already: Will, Tapani, Ken.) It only takes a minute, and it makes much easier for people to find your work, especially after some time has passed. Plus we end up with a public repository of our best efforts. all the best, G.

No loud audio on Fedora 11 x86_64

by lanas

All, There is seemingly a problem with having loud audio on Fedora 11 x86_64 on a recent ASUS mainboard using the Nvidia audio interface. The Nvidia app has all volume controls set to 11 so to speak, and the audio hardware volume knob all set to the max but still, no loud noise. alsamixer will only return 1 control, which is set to 100 and kmix will seemingly not start. Of course, PulseAudio is in full force. This also affects Qsynth and Zyn outputs when jackd is running. Is this a known problem or is it local to that machine ? Thanks.

Strange aiff files

by Atte André Jensen

Hi I'm having trouble opening a few aiff files, that were send to me by someone. They were originally part of a recording session in (I think) protools on a mac. Probably they were saved to CDR and handed over to the windows user that has mailed them to me. They are longish bounces of vocal takes. Anyways, the problem is that they open different each time. Sometimes the first part is missing, sometimes the last part. I tried opening them in both mhwaveedit and Renoise. The sender checked and the files have exactly the correct content on her computer. What could be the problem here? Is it in fact something else that I didn't think of that is at play? I don't know about renoise, but isn't it so that almost every audio app is using libsndfile for opening/converting-from aiff files? So I should expect similar results in all apps, or? Is there a way to check the problematic files to get closer to the problem? Is there a conversion I should try (tried my a2wav script that uses mplayer, still some parts missing). NB: This is with a super-fresh install of ubuntu 9.10 -- Atte http://atte.dk http://modlys.dk http://virb.com/atte

Anticipating - a new song from Meditera Production

by Viktor Mastoridis

Well, it's the season of music presenting I guess, so here's my bit: http://mastoridis.co.uk/temp/linux/Anticipating.ogg Anticipating a simple tune with a few challenges set. 1. To make a v simple chord progression interesting for 3 mins 2. To start the collaboration with Richard Miles. Richard is a colleague of mine and a science teacher. Last year he discovered his amazing talent for poetry and already wrote 15 samizdat (self-published) poetry books. I sent him the basic idea, and he returned the lyrics, basically;-] 3. To further learn the art of final production on Linux Audio. This time using the wonderful Linux DSP suite on AVLinux - particulary the Valve Compressor and the Graphic Eq while mastering. The vocals and bouzouki use the Linux DSP Reverb as well. Critical comments (deserved) and praises (undeserved) are welcomed. -- Viktor Mastoridis Music-o-Graph & Educator www.MediTera.Co.Uk

vlc auto connect to jack

by Atte André Jensen

Hi I'm using vlc to play audio through jack, and although it seems to have been working in the past, it's not really at the moment. The problem is that vlc is not connecting to jack and I can't make a rule in the patchbay, since vlc appends the process number to the jack client name. Any solutions or ideas? -- Atte http://atte.dk http://modlys.dk http://virb.com/atte

Re: [LAU] Audigy soundcard silent after upgrade to Ubuntu Studio

I have the Audigy2 card in this ArtistX/Ubuntu 9.10 Dell > Workstation, and it is fully functional. Amazing! Eureka etc. Thanks very much indeed, Frank. I've put about 15 hours into this problem and you've solved it. Now the question is, how did a bad asound.state file get created as a default during installation? Does anyone know where I should go to alert someone who can look at this? Here is a comparison of the good and bad asound.state files. The replacement asound.state file has 227 controls vs 216 for the oroginal. The following 14 switch controls existed only in the good file. The Master Playback Switch only existed in the good file. If it exists on the sound card and is muted by default, there would be no sound output. There are 3 possible duplicated controls. control.1 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Front Playback Switch' value.0 true value.1 true control.2 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Surround Playback Switch' value.0 true value.1 true } control.3 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Center Playback Switch' value true } control.4 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'LFE Playback Switch' value true } control.5 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Side Playback Switch' value.0 true value.1 true control.7 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'CD Playback Switch' value.0 true value.1 true control.9 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Line Playback Switch' value.0 true value.1 true control.11 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Mic Playback Switch' value.0 false value.1 false control.12 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Front Mic Playback Switch' value.0 true value.1 true control.13 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Headphone Playback Switch' value.0 true value.1 true control.15 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Capture Switch' value.0 true value.1 true control.20 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'IEC958 Playback Switch' value false control.21 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'IEC958 Default PCM Playback Switch' value true control.22 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Master Playback Switch' value true ----------------- The following controls existed in both files.
