Updating PulseAudio to Nightly Build

Warning — This did not work, and I ended up going to Fedora instead!  So, don’t try this at home!

I just tried to record a tape by hooking the headphone jack of my stereo to the microphone jack on my laptop. I used Audacity to try to record the tape, and it would have worked if it wasn’t for a bug with Ubuntu/PulseAudio. My laptop would only record from the built-in microphone. It acted as if the external mic jack wasn’t even there. I tried to adjust settings in the audio settings and the alsa mixer. Nothing seemed to fix it.

So, I decided to try to update Pulse. This is risky, but hey, it wouldn’t work anyway. Why not make things worse!

First, I checked my current version.

skp@pecan:~$ pulseaudio --version
pulseaudio 0.9.22-24-g67d18

Then, I tried to install the “PulseAudio daily builds” PPA. Here’s the command:

skp@pecan:~$ sudo add-repository ppa:ubuntu-audio-dev/pulse-testing
[sudo] password for skp:
sudo: add-repository: command not found
skp@pecan:~$ sudo add-apt-repository ppa:ubuntu-audio-dev/pulse-testing

gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

Next, I opened update manager:

skp@pecan:~$ sudo update-manager
[sudo] password for skp:

Now, I realized too late, that I hadn’t done an update yet, but I found I had a few pending updates that I didn’t know about. So, I installed those first before worrying about the pulse updates.

Then, I clicked the “Check” button and I saw all of the pulseaudio updates. So, I installed once again.

Now, the pulseaudio version is very weird!

skp@pecan:~$ pulseaudio --version
pulseaudio 0.98-201107121852

Update: I just tried my mic out in Fedora 15. Audacity records correctly from the external mic when it is plugged in and the built-in mic when the external is not. Many other things in Fedora don’t work, but sound works well!
