Ubuntu: No sound after suspend to RAM fix
Posted in Ubuntu Tweaks .:. No comments yet
The magic of open source software is evident every few days or so when the Ubuntu Update Manager notifies me of another round of bug fixes and/or security patches. Over this past winter break, I put a new motherboard (Foxconn M7VMX-K) in my computer and decided to test the “sleep” function. Since Ubuntu relies on community testing, hardware support can be a weakness and sleep did not work with my old mobo. However, I was excited to see that my computer properly slept and woke-up with this new motherboard… except for one problem. After waking up, the sound did not work! Frustrated, I did a Google search and found a thread on Launchpad (the Ubuntu bug tracking site) which seemed to describe the issue I was experiencing as well as a workaround. For anyone interested, the fix is to run the following commands after resuming:
pulseaudio -k
pulseaudio -D
A few weeks later I spotted an update to pulseaudio on update manager with the description “Add pm-utils sleep hook to suspend (and resume) users’ pulseaudio daemons”. That sounded promising so I quickly installed the update and put my computer to sleep. Sure enough, after waking it up the sound worked!
