No sound after Xubuntu-desktop installation

Question

I had, initially, a Ubuntu installation running completely fine. Compiz bugged, then I switched to LXQT.

LXQt bugged between sessions, then I switched to KDE. KDE bugged on some applications, then I switched to XFCE (at the moment).

Sound worked fine between all those transitions up until now. When I finally installed and rebooted my PC, sound was gone.

I'm running Ubuntu 14.04 x64 on the XFCE Enviroment. Switching to another session/enviroment doesn't work.

What I've done already:

• Reinstall alsa and pulseaudio (purging)
• Add a string line at the end of alsa.conf
• Check if my audio drivers are being detected
• Try unmuting sound values on the xfce4-mixer
• Purging pulseaudio and trying to work with only alsa
• General information I found on the similar topics didn't work either
• Tweaking values on alsamixer

Any help would be appreciated. As I said, problem started when I installed Xubuntu.

I was told to remove xfce4-mixer but I had to uninstall the xfce4 package along it, should I proceed?

Solution 1

I resolve with pavucontrol. sudo apt-get update sudo apt-get install pavucontrol

Select the device and remove mute sound.

Solution 2

OP HERE

Aswering because I've been able to narrow down my problem.

It seems like Xubuntu comes with Pulseaudio by default. It seems like Pulseaudio overrode my ALSA native settings, becoming the main output device. The problem here is that PulseAudio won't detect my onboard audio chip, only the GPU one that I won't use.

If I try to uninstall Pulseaudio, however, ALSA won't naturally take his place. I tried to open a music on VLC to test after uninstallid pulse and it said "No default output device ...".

So I need to do either:

1. Force PA to recognize my onboard card
2. Uninstall PA and make it my default device for outputting sound

I can't play a sound with aplay, by the way.

do you have a file for /etc/pulse/default.pa? if not, copy and paste the contents of this pastebin.com/EJ2qvZvA to make that file, save it as /etc/pulse/default.pa and reboot. I HATE it when that happens, it's sooo annoying.

Try with sudo apt-get install build-essential linux-headers-uname -r

Hey, the default.pa thing didn't work. I already had a file with that name created at the directory, changed it's name and replaced with the pastebin version... Didn't solve. Neither did the linux-headers. pastebin.com/GCeKzMj8

Remove pulseaudio (sudo apt-get remove pulseaudio) , reboot and test (you will then use alsa layer only). Also remove the line you add in alsa.conf (but did you test "generic" ?)

Hey, I was able to narrow down my problem and posted it below! As I said in the main post, I've already tried to work around with only ALSA and it didn't work

omg, you provided the simplest and oneliner that solve the thing for me: just need one tool to let me choose all the different audio configuration: in my case, pavucontrol - i switch the output device from analog output to headphone as output. Thanks.

you're my savior.. xfce-mixer hanging, pavucontrol runs fast XD
