After installing Ubuntu 20.04 on my desktop computer (Realtek onboard sound card, codec ALC887), I am experiencing a very annoying click (popping sound) every time I open any content with audio.
After I have installed Ubuntu 12.04 LTS (32 bits), Firefox 12 works fine but without hardware acceleration. Needless to say I have the latest nVidia's proprietary drivers installed and my Firefox Preferences, on "Advanced" tab, "Browsing" section, have the option "Use hardware acceleration when available" checked.
I have tried the following things before asking this question:
- Creating a boolean key "webgl.force-enabled" and set it to true on Firefox's page about:config;
Starting a new profile like commented on thread Mozilla Firefox 12 is very slow on Ubuntu 12.04 LTS;
I have updated my nVidia driver to version 295.53.
And none of this have worked. As you can see below in my Firefox's page about:support report, "Graphics" section shows no "GPU Accelerated Windows":

I use the following site to test hardware acceleration:

On Windows 7 I get 60 fps even with 1,750 fishes on browser's Full Screen Mode (1680x1050x32bit-color). On Ubuntu 12.04 LTS, same nVidia drivers (as shown in report), won't go faster than 15 fps with only 1,000 fishes.
Can anybody help me?
