After working happily a couple of months with Ubuntu 10.04 I installed a new kernel with the update feature. This resulted in not having any sound or volume controls. After reading a lot on internet articles I found the following article… Comprehensive Sound Problem Solutions Guide v0.5e I followed the following commands that brought back sound to my notebook.
Getting the ALSA drivers from a *fresh* kernel
Sometimes, sound might be configured correctly, but for some reason or another (tinkering) it stops working. One way to go back to the old setup is to reinstall Ubuntu. However, this step is actually quite unnecessary since you are reinstalling everything because of one thing.
A faster way, is to just remove the problematic packages and reinstall them cleanly.
Step – 1: Remove these packages
|sudo apt-get –purge remove linux-sound-base alsa-base alsa-utils
Step – 2: Reinstall those same packages
|sudo apt-get install linux-sound-base alsa-base alsa-utils
VERY IMPORTANT NOTE: Ubuntu (GNOME) users have reported that packages ‘gdm’ and ‘ubuntu-desktop’ are removed after removing the linux-sound-base packages. If this happens, then do the following
|sudo apt-get install gdm ubuntu-desktop
Step – 3: Reboot
As I upgraded Ubuntu Studio 12.10 to Ubuntu Studio 13.04 on my Mac Book 5.1 my wireless stopped working… After surfing the internet for a couple of days I’ve found the following solution to enable the Broadcom STA on my Mac Book 5.1.
Check whether Ubuntu sees your Broadcom STA device by running the lspci command from a terminal:
After using the the lspci command you should get something like this:
03:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)
Next up is, installing the drivers. To install the drivers run the following command using the terminal:
|sudo apt-get install firmware-b43-installer
The broadcom-sta-common package, blacklists the b43 driver.
To fix this you need to edit the file: /etc/modprobe.d/broadcom-sta-dkms.conf
You can do that by using the following command in the terminal:
|sudo nano /etc/modprobe.d/broadcom-sta-dkms.conf
Delete or comment out with a “#” the line “blacklist b43”, my file looks like this:
|# wl module from Broadcom conflicts with the following modules:
# blacklist b43
Then to force the module to load during boot by using the following command in the terminal:
Then add a line with “b43”, my /etc/modules file looks like this:
|# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.
You don’t need to reboot your computer as you can load the module manually by entering the following command in the terminal:
