Hi. I have the same problem in the Medion Akoya P6687 - MD61006. After upgrade the BIOS at the latest version (same as lms2 user) the sound stop working. Reading in internet I'm pretty sure that the problem is that the BIOS have disabled the sound card. In Windows the Speakers are marked as "Unplugged". It is the second laptop of that model the shop have sent me and in both cases is the same. Please, I encourage to Medion to ask InsydeH20 to provide a new BIOS software upgrade that solve that issue. Thanks in advance.
