Please try the same solution which is already written in this topic.

Exit Audacity, open a Terminal, type the following:

Code: Select all

env PULSE_LATENCY_MSEC=30 audacity

hit ENTER on your keyboard then Audacity will launch.

Alternatively, choose the (hw) playback device or dmix in Device Toolbar .

Sorry, I didn't see this solution, because there was so much talk about multiple programs using the soundcard, which wasn't happening in my case, So I didn't pay attention.

Linux is so frustrating sometimes. I've been using Audacity for years with different version of Ubuntu, and it decides to break with a new version.

Anyway, I tried the HW playback device option and it works. Thanks you very much!

As a general point, Ubuntu is an early adopter of new technology and new versions. The plus side is that Ubuntu users get to be among the first to try out the latest and greatest software. The downside is that breakages are more frequent as new software is exposed for the first time to millions of users. Some other distributions (notably "Debian Stable") update applications more slowly, so by the time it reaches the end user it is thoroughly tested. The plus side of this approach is a stable system and breakages are rare. The downside is that applications may be a few versions behind the latest release versions. Mint is a very popular distribution based on Ubuntu. Because Mint lags a short way behind Ubuntu, main bugs and breakages are caught by the Ubuntu team before they reach the Mint releases. One of the benefits of using Linux is that you are free to choose a distribution that suits your tastes and needs.

i had though the "dmix" setting had solved the freezing problem, and it seemed to for a little while, but then Audacity froze up while hitting play/stop (using the spacebar), i'm running linux mint 17, audacity 2.0.5, 16gb of RAM, 100s of gb's of harddrive space.
argh.

Hi, Guys,

Hardware: Thinkpad P51
OS: Ubuntu GNOME 16.04

I tried the suggested "fix" for this by using Terminal with this command:

~$ env PULSE_LATENCY_MSEC=30 audacity

Problem didn't resolve, but I got the following list of messages, that I hope will be helpful:

I'm a linux newbie / recent Windoze convert, and hoping for some help with this.

Thanks very much!
