I am new to this forum but I have looked prior to posting my question. I have successfully installed Lion on my D620. I have also updated it to 10.7.4. I have only one issue. I have no sound. There is nothing in system/sound for a device to choose from. I did add sunflower and it has no helped. I couldn't find any other post with no sound device available. I some one could point me in the right direction I would appreciate it.
Thanks
