Audacity on Ubuntu 14.04 is REALLY unstable

by Alan McKay

Hi folks, I took Audacity out of apt and wow is it unstable. Constantly hanging. At least it is able to recover most of the time after a restart - except for once last night where I lost my LP rip. It was bearable before then but now I want a better solution. Is anyone else having this problem? Any solution in mind? Should I pull down one of the daily builds from Audacity and try it? Or build from source or something? My Ubuntu is fully updated. I was also thinking of trying CentOS7 to see how that does. thanks, -Alan -- "Don't eat anything you've ever seen advertised on TV" - Michael Pollan, author of "In Defense of Food"

Re: [LAU] Internal speaker set as default playback, not my usb soundcard.

by Andrew C

Excellent, thanks for that tip, Phillip! Got it fixed now. Put "autospawn = no" into $HOME/.config/pulse/client.conf, killed PA as you suggested and everything worked as expected, alsamixer controls the volume (.asoundrc works perfectly again) and mplayer/flash/MOCP plays through my usb card.

Re: [LAU] [Bulk] Re: Audacity on Ubuntu 14.04 is REALLY unstable

Well, I've heard that Gnome 3's default configuration makes it a major resource hog - particularly for memory. Like KDE4. I avoid Gnome 3. Both it and KDE4 launch a bunch of system services that I think can really impact RT use. Sorry, I don't know anything about how Fedora might be configured differently from Debian.

Internal speaker set as default playback, not my usb soundcard.

by Andrew C

Hello all, Recently did an upgrade to Ubuntu 14.04 from 12.04. All went well except I've encountered a very weird problem. My usb audio is no longer the default sound card. I had to some some trickery (made snd-usb-audio=-1 and snd-hda-intel=-2) in /etc/modprobe.d/alsa-base.conf to get the usb card as #0 as listed by /proc/asound/cards and then I got all sound going out through my usb card. Fun fun fun. Now with Ubuntu 14.04, my usb card is still listed as #0 in asound/cards, but mplayer defaults to my internal speakers when issued 'mplayer sound.wav'. Also tried: mplayer -Dalsa=hw=0.0 sound.wav Plays through my usb soundcard mplayer -Dalsa=hw=1.0 sound.wav Plays through my internal speakers mplayer -Dalsa=plughw sound.wav Plays through my usb soundcard mplayer -Dalsa=default sound.wav Plays through my internal speakers. Also I tried opening 'pavucontrol' fwiw and disabling the internal speaker. Playing a sound file without any other options via mplayer sends the sound through my usb soundcard. This is really strange and perhaps I'm not entirely understanding all the "wonderfulness" that is alsa. Cheers, Andrew.

Ubuntu Studio (was: Audacity unstable)

by Alan McKay

Hey folks, I'm thinking I might just install Ubuntu Studio tonight and run with that. The website does not seem to tell me the essential differences from Ubuntu. Which desktop is used? Are there any other major differences I'll notice aside from this? thanks, -Alan -- "Don't eat anything you've ever seen advertised on TV" - Michael Pollan, author of "In Defense of Food"

JACK not working with Audiophile 2496 anymore

by david

I get these messages from JACK when I start it using QJackCtl, trying to use my AudioPhile 2496. This is running on Debian Sid, uname -a reports "3.14-2-amd64 #1 SMP Debian 3.14.15-2 (2014-08-09) x86_64 GNU/Linux" (but I was getting the same error on kernel 3.02.4 before that.) I am a member of the audio group. JACK starts and runs fine if I pick the "default" interface, but that doesn't play any audio through the Audiophile. (I have no idea what it's playing through.) While parts of Pulse are installed, according to "killall pulse" Pulse audio is not running. Trying to remove the installed Pulse packages wanted to also remove a bunch of other apps, such as csound, GIMP, some KDE4 apps, etc. I found an old thread on a forum where the poster said installing "dbus-python" fixed it, but the closest package I could find similar to that name is "python-dbus" and it's installed. This is a fresh Debian Sid install and my first experience with Debian's move to systemd instead of good old reliable init, so could that be messing things up? Or that it's using PAM (my prior Debian experience didn't include PAM) and htop shows a number of (sd-pam) processes running)? jackdmp 1.9.10 Copyright 2001-2005 Paul Davis and others.

I tried disabling the motherboard audio, but then ALSA wouldn't load at all. My replacement desktop system is too modern to support such old equipment as the Audiophile, it would be nice to have it working in the old desktop system where it worked fine for many years, but now no longer works. -- David W.

Seeking computer musicians for a survey on how do computer musicians develop computer musical instruments or applications?

by Abram Hindle

Hello, I apologize for the intrusion but the linux audio users list hosts exactly the people we are looking for: computer musicians who code. We're trying to figure out how software engineering research can help computer musicians or if computer musicians need any help. Are you a computer musician? Do you code in languages geared towards music (e.g., Pure Data, Max MSP, Chuck, SuperCollider, etc.) or make music in other programming languages like C, Java, C++, Javascript, etc.? If so, we would like to hear from you! We the PIs, Gregory Burlet and Abram Hindle, are from the Department of Computing Science at the University of Alberta and are conducting a survey of computer musicians to investigate how this demographic of software developers program musical instruments or applications. Please visit the survey invitation website <http://webdocs.cs.ualberta.ca/%7Egburlet/musiccoders_survey.html> and click the "I consent, take me to the survey" button to complete the survey (if you consent). The survey will take 5 to 10 minutes. http://webdocs.cs.ualberta.ca/%7Egburlet/musiccoders_survey.html Thanks for your time!

vsts and wine startup times

by James Stone

I have been playing around with a new program that does win->linux vsts called airwave. It seems pretty nice as it does xembed properly so all menus etc. appear correctly, and the vst performance seems acceptable (fewer xruns than vst-bridge). I hit a problem when first running it which turned out that it was due to the host not waiting long enough for the vst to initialise. It hard coded a maximum wait of 3 seconds.. Whereas on my system, wine takes around 24 seconds to start first time or around 4 seconds on subsequent times. I have been in discussion with the dev about increasing the timeout. He changed it to 8s which works OK apart from first run on my system. So my questions: 1) what is the longest startup time for wine that would be reasonable to assume? 2) is 24 seconds abnormal for a reasonably recent (last 3years - AMD A6-3670 ) desktop system? James
