Default View Mode: Waveform (db)

Using Synaptic for sound optimization

I just installed a few files with Synaptic following this sound guide. Interesting tip:

“With jaunty (not sure about intrepid), try this:

pulseaudio –kill

then

sudo alsa reload

It’s worked for me everytime so far, but it has to be done during a user session.”

Good tip, but I won’t try it because Audacity is able to record and Totem is able to play wav files at the moment. But how is it possible to play sound with simon?

Here is another interesting tip. Maybe I should take a closer look at Mint. By the way, this could be an option for the PC that is connected to the video beamer for playing DVDs.

My sound configuration

Here are a few screenshots of my sound configuration. I am not satisfied at the moment. Ubuntu is much more complicated when it comes to sound than Win XP. I am trying to find a better configuration than my current one:

Sound Preferences

Sound wave doesn’t look perfect under Audacity

I want a cleaner sound wave under Audacity. It should sound better than now.

Audacity preferences

I will do some trial and error to find a proper solution. Maybe I will install JACK.

I just found some useful tips. I just read a few lines and checked the volume control on the panel. I adjusted a value. It is better now.

JACK and Audacity

Sound is often a problem under Ubuntu Linux. But I think that I have solved this problem on my computer. Let’s take a look at the following screenshot.

You can see on the left side the JACK audio connection Kit. And on the right side you can see how I am installing Audacity.

It is necessary to experiment with the Audacity preferences. The recording device has to be set to the JACK audio connection Kit system. I had to do a lot of trial and error. But in the end, it worked and is still working.
