I report this as a cautionary tale. Tonight I suddenly lost sound output from my 3.5 inch output from my iMac. Several reboots did not solve the problem. I went into recovery console to reinstall OS but was dismayed to find that only the option to re-install Mavericks was present. . As I had no choice I selected this option. However three attempts at re-installing Mavericks failed as I had Yosemite already installed. I somehow thought that Apple would not possibly have removed the recovery console ability to re-install, but they had. What I eventually had to do was erase everything on my hard disc in disc utility and I was then able to install a clean install of Mavericks. I then in mavericks tried to install the Yosemite update but my Mac was unable to download from the store. Luckily I had saved a copy of the original Yosemite install file and I was able to locate this and run this. Then after installing Yosemite I had to run all the updates and finally used the migration assistant to copy all my apps at across from my Time Machine.
All in all it has taken me about 4 hours to complete the process but at least I can hear Voiceover again through my -headphones and do not have to rely upon speakers. Why Apple has not update the Recovery Console so that it supports Yosemite is very strange. Essentially you can no longer do a re-install with the recovery console now and you are restricted to clean installs of Mavericks and then after that upgrading to Yosemite. I will have to inquire about bootable media to run re-installs from but I thought that was the whole point of the recovery console. Checking on Google there are quite a few experiencing the same issue and complaining.
