I am using Ubuntu 12.04 and Skype.
My mic is not working. I have 1 mic attached to the system and another one in my headphone (Beats by Dr. Dre).
I followed these steps:
Turn PulseAudio autospawn off, normally: $
echo "autospawn = no" > ~/.pulse/client.conf
But this did not help me and it disabled my sound after my system restarted. I then tried
echo "autospawn = yes" > ~/.pulse/client.conf
It fixed my system sound but still no sound on Skype microphone.
After that, I tried this command
echo "options snd-hda-intel model=acer" | sudo tee -a /etc/modprobe.d/alsa-base.conf > /dev/null
I've also upgraded alsa sound drivers by running:
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa sudo apt-get update sudo apt-get install linux-alsa-driver-modules-$(uname -r)
however on the last command:
sudo apt-get install linux-alsa-driver-modules-$(uname -r) [sudo] password for gaurav: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package linux-alsa-driver-modules-3.2.0-27-generic-pae E: Couldn't find any package by regex 'linux-alsa-driver-modules-3.2.0-27-generic-pae'
When I type
pulseaudio in terminal it shows me
E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed.
After all this, my sound system started behaving abnormally. Internal Speakers and headphone or 5.1 speakers both works at same time but still the microphone is not working. I even hear a noise when I don't play anything. It's freaking me out and my microphone problem is after 12.04 . Can I use my headphone microphone? I am having beats headphones.
