the correct driver for the non-HDMI sound device).ДЄfter rebooting a few times, the sound started working consistently and up til now i've not yet lost sound. So theoretically the only driver installed on Location 0 is now the Sound Blaster Recon3Di driver (i.e. So with this theory in mind, I started up the laptop, and when I noticed that the duplicate driver was appearing in Device Manager in Location 0, I quickly uninstalled it before it could disappear. This would explain why the sound never disappeared anytime the laptop was turned on, but only when it was being started up. The times that the sound did work was probably when the sound blaster driver got initialised before the HDMI one.almost like a race condition upon bootup. So I'm guessing that the HDMI sound driver for the audio port had somehow installed itself on the speaker/headphone device, and was causing the device to not work. In the Properties screen it says it uses Location 0, which is the same location as the duplicate High Definition Audio Device that appears temporarily before disappearing (when the sound doesn't work). I have observed that when the sound is actually working, there is a 'Sound Blaster Recon3Di' device installed in Device Manager under Sound, Video and Game controllers, which isn't there when the sound isn't working.

Is it possible for this Code 45 device error to occur where the problem isn't hardware related? I'd like to check with you guys if anyone has encountered this issue before, and if it really must be a hardware issue.Д®.g. Now that just seems to scream 'loose audio connection/cable' on the motherboard doesn't it? To fix this problem, reconnect this hardware device to the computer' I'm thinking it may be a hardware issue because when I log in and check the device properties on one of the sound devices labelled High Definition Audio Device, the device status indicates: 'Currently, this hardware device is not connected to the computer (Code 45) It's been hit and miss and I'm really frustrated why sometimes the sound works and sometimes it doesn't. In the end I just give up and the next morning I turn on the machine and the sound works fine! I've tried disabling all sorts of services/startup options in msconfig to try to isolate the problem but no luck.

I've tried uninstalling the sound driver via Device Manager and restarting, and checking for updated drivers but that hasn't helped. The one remaining indicates 'not plugged in'. Right clicking the icon and going to 'Playback devices' brings up a window with 2 'Digital Audio (HDMI)' devices initially, but then 1 disappears after a few seconds after logging in. On occasion after logging in to Win7, the audio icon in the taskbar is crossed out and a mouse over reveals the message 'No speakers or headphones are plugged in'. It's been a bit over a month since getting a brand new M14XR2 laptop and I'm finding that the sound just disappears every now and then after turning off the machine.
