Hi I've been experiencing a bit of weirdness with my soundcard for quite a while now, maybe as much as a year. Often, but not always, when I start my machine I'll only get sound from the left channel. I found that I need to open the control software (used to be Envy24 until I upgraded to Ubuntu Studio 12.04 last year, it's been Mudita since then) and play with the analogue volume control. Both left and right volume controls are set on maximum, but as soon as I move the right-hand one (down and back up to max) I get stereo sound again. I swapped the card for another one and that didn't solve it. I have a permanent /home and my OS on a separate partition -- could this be caused by a config file somewhere on /home and if so, where might I find it to sort this problem out? Thanks in advance Q

[LAU] alsamixer in 12.04: what's the low down on "pcm" vs "headphone"

by Aaron L.

Two meters that seemingly do the same thing. But not. PCM seems hotter and more brittle. What's the deal with these?

Re: [LAU] Renaming/aliasing ALSa sequencer hardware clients

by Ralf Mardorf

Hi Julien, it's not an answer to your question, but already an assumption, since QjackCtl only provides to show aliases for Jack clients, I guess there are no aliases for ALSA MIDI devices. If aliases should be available, it would be interesting for me too, because 2 of my MIDI interfaces share the same name. Card 1: TerraTec EWX24/96 at 0xbf00, irq 20 Card 2: TerraTec EWX24/96 at 0xbb00, irq 21 The different IRQs and card numbers aren't helpful for auto connecting MIDI, at least not in the ways I did it until now. Regards, Ralf

[LAU] 32 vs 64 bit distro?

by James Stone

Is there any advantage in using a 64 bit distro for audio? Do the advantages outweigh the difficulties? I'm expecting a new computer to be delivered today and am trying to decide what to install... Thx, James

You need the right medicine at the right time. Old school Rock'n'Roll Listen to the original music copied by The Brian Setzer Orchestra. It's not my kind of music, but The Brian Setzer Orchestra already is good, however, if you want it more musical, take the time and really listen to the originals. I more and more win the impression that here's too much bias regarding to what we call "U" and "E" music in Germany. Extraordinary abilities seem to be more important, than the heart. Not kidding, music battles, not by email, really, on the stage, become more and more hip in some scenes. There really are contests! For me this is the opposite of music. For music means playing together. I don't dislike Dieter Bohlen, regarding to his limited abilities, I dislike him regarding to the way he does misuse his abilities. I could say the same for some very gifted musician. Extraordinary abilities are a nice feature, but not needed to make nice music.

Re: [LAU] Changed: Copyright laws and such

I want to live forever. What > next? But that is important! Because we talked that much about money, an easy to understand example. There are rich people and some poor people are unhappy because there are some rich people. To become happy the first way to go, is o find out what _you_ and not _somebody_ else wants. If you want to be rich yourself, you simply don't like rich people, because you are envious, you won't become happy, when all the rich people become poor too. In this case you shouldn't fight against the rich, but find a way to become rich yourself. If you are unhappy regarding to empathy, because you think that the universe isn't a strawberry field, but a hard, unfair place, you'll not become happy if you become rich too, you need to work for a fair and lovely world. It's not important to become rich, if you want to become rich, it's not important to get a perfect world, if you want to get a perfect world. It's just important to go the way that's close to what you want, this will make you happy. So what kind of copyright or copyleft does provide the most freedom for everybody, to go the way that makes happy? The only important thing is exactly this freedom.

What drives > them to do this to bands they love? If people like a band, they will find a way to give them money, so that this band can record more songs for the fans. Real musicians have fans that like to pay for the music. Piracy only is an issue for the most worse and hyped music from the top 40, since it's an artificial situation, no fan expect that one of those day flies will stay for very long, soon or later there will be the next fashion. I won't imagine what will come next, after this loudness and auto-tune fashion. Without heavy rotation nobody would like the crap they call music. I for sure had nearly all Beatles recordings as illegal copies on tapes, but I also bought all of this recordings, without expecting that the Beatles ever will record a new song. I never owned music from The Black Eyed Peas as illegal copy or bought recording. They sell an entertainment product, that has less to do with an intellectual property. It's based on an exhausted fashion. The current copyright is a dying concept, because it's completely outdated, it's from another time. Major record labels, computer companies search for new ways to rip off customers by getting as much monopolies as possible. The idea of the outdated copyright was not to protect monopolies. Monopolies aren't allowed. The artist from the neighborhood still has some advantages by IP laws, but the complete package of laws is a pack of disadvantages and only good for a few big moneymakers. Unfortunately most humans can't share, most humans need enemy images etc.. All the 80s European DIY movement Punks, such as Crass didn't become rich, but they still are able to live. There's no need to be rich. I feel bad for people who are unable to walk in shoes with wholes in the sole. There's nothing bad with having money, but it's no problem to live with less money. I've got the impression this discussion about IP, copyright is about money, money, money. What's about freedom, sharing knowledge etc.?

[LAU] More jack woes

by Bob van der Poel

Okay guys ... a few weeks ago I got jack running with audacity. Couldn't have done it without your help. But, this was with a dirt cheap Behringer usb interface. Which I thought might not be the greatest. Today, my new and improved Presonus audiobox USB arrived. After changing a few names in my startup script ... it all seemed to be working. Until I tried to record using audacity. Remember, this worked fine with the cheapie. Now I get a series of xruns: This is snipped from my terminal. Not sure where the audacity stuff stops, but better too much? Expression 'ret' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1670 Expression 'AlsaOpen( &alsaApi->baseHostApiRep, params, streamDir, &self->pcm )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1830 Expression 'PaAlsaStreamComponent_Initialize( &self->capture, alsaApi, inParams, StreamDirection_In, NULL != callback )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2092 Expression 'PaAlsaStream_Initialize( stream, alsaHostApi, inputParameters, outputParameters, sampleRate, framesPerBuffer, callback, streamFlags, userData )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2764 Expression 'stream->playback.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 4541 Expression 'stream->playback.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 4541 Expression 'stream->playback.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 4541 Expression 'stream->playback.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 4541 JackEngine::XRun: client = PortAudio was not run: state = 2 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = PortAudio was not run: state = 1 The recording works, but it compressed/expanded and is totally useless. I'm having audacity play back a stereo track while recording one. So, did I but the wrong bit or hardware? I did check and it seems to be a workable unit. -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Hi John :) I've got difficulties to completely understand your whole mail, perhaps regarding to my broken English. However, the windows managers and desktop environments might need 3D support and similar things, if you're using special desktop effects, so it can be, that a desktop environments needs this, e.g. 3D acceleration, as being provided, but it's provided by X (for some users perhaps by Wayland instead of X). For your Ubuntu Studio Xfce shouldn't need 3D acceleration or any other special option. Xfce can be used with or without the proprietary NVIDIA driver. What kernel do you run exactly? What's the output of uname -a ? If it's a PREEMPT RT, than it's very likely that the proprietary driver can't be used with the kernel. If it's a full PREEMPT kernel with threadirqs activated, the proprietary driver should work. Any output for $ grep EE /var/log/Xorg.0.log ? Regards, Ralf
