Hello David, First, let me say that I am so sorry you had to go through all of that just to get back up and running.
Second, I am wondering why you lost sound in your 3.5 earphone/microphone jack. If you don't track down the cause, or at least an easier solution, you may have to deal with such an issue in the future. I'm curious: did you check your audio output settings in system preferences or in the application-specific preferences before resorting to reinstalling the OS? I'm almost certain you did but just wanted to ask. A month or so ago, I removed and reinstalled several versions of Audio Highjack Pro. A couple of days ago, I was helping a friend test Skype and discovered that, while the built-in microphone worked, when I plugged in my Apple wired headset, she could not hear my voice. As it turned out, I discovered in Skype Preferences that one of my audio settings had been switched to Sound Flower. Thinking back, I do remember experimenting with Sound Flower back when I was working with Audio Hijack Pro. I was so glad I first checked the audio settings in Skype before uninstalling the application. As for the recovery partition: A couple of months ago, I purchased a 13 inch, mid-2014, MacBook Pro with Retina display. The machine came with Maverick. I subsequently updated it to Yosemite. Before making a Yosemite install USB Drive, I had need to re-install Yosemite using the Recovery partition. Upon using the startup key combo of Command+R, and of course starting VoiceOver after system Startup, I was given the option of re-installing Yosemite and only Yosemite. Now that I think about it, again, before making a USB Yosemite install key, I performed the same steps on a friend's MacBook Air which, like my Pro, had originally shipped with Maverick, and was able to re-install Yosemite from the Recovery partition. Now, of course, I have a Yosemite install key so have no need to use the Recovery partition but, for me and my friend, at least, the Yosemite Recovery partitions performed as expected. After doing a little research on this, a few minutes ago, I learned that Recovery Partition mileage may vary depending upon when the Mac was purchased and the type of Mac in question.

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.
