When I type pulseaudio in terminal it shows me E: pid.c: Daemon already running.Į: main.c: pa_pid_file_create() failed.Īfter all this, my sound system started behaving abnormally. However on the last command: sudo apt-get install linux-alsa-driver-modules-$(uname -r)Į: Unable to locate package linux-alsa-driver-modules-3.2.0-27-generic-paeĮ: Couldn't find any package by regex 'linux-alsa-driver-modules-3.2.0-27-generic-pae' Sudo apt-get install linux-alsa-driver-modules-$(uname -r) I've also upgraded alsa sound drivers by running: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa It fixed my system sound but still no sound on Skype microphone.Īfter that, I tried this command echo 'options snd-hda-intel model=acer' | sudo tee -a /etc/modprobe.d/nf > /dev/null

I then tried echo 'autospawn = yes' > ~/.pulse/nf Turn PulseAudio autospawn off, normally: $ echo 'autospawn = no' > ~/.pulse/nf killall pulseaudioīut this did not help me and it disabled my sound after my system restarted.

Skype echo sound test gone
