I have been following the "No HDMI Audio" threads and posts here and elsewhere- guess why!
Actually the saga is longer and broader than that but this was the remaining unresolved issue. Unfortunately I haven't kept a log but I'll give a brief rundown of what I've done so far over the past 4 or so weekends.
Note the cost in my time now vastly exceeds the cost (or value) of this device. Intel take note!
Also this is the 2nd Win10 device (out of two- the other is a Dell XPS13) that has failed from the initial install. So forgive me if I'm a bit leery of the whole Win10 thing.
So here's my not-so-abridged saga so far.
- Tried starting up the device. It never did.
- Eventually (with the help of another working computer) figure out how to get into the restore/fix bootup menus- luckily they were there, it was a close run thing to it being bricked/DoA. Of note: the stick was plugged into a DVI monitor (i.e. no sound) at the time through an adaptor plug.
- Tried the various restore/fix procedures in the menus this and that, eventually (after one wasted weekend) having to do the full wipe & reinstall from scratch to get it to work at all (phew!). By this stage, it's connected to HDMI TV. Of course, this takes a few hours.
- Get a basic running level, network connection (I think) and even manage to run SFC and DISM to check the files.
Note all the above takes place whilst I use the resources at exceedingly tolerant grandparents'-in-law's house. It was meant to be a test as a replacement computer for them- plug it in the back of the monitor, they can do their emails a a bit of browsing whilst saving power and space over their current box which they leave on 24/7 (no I can't change their habits). Sadly, this does not seem to be a viable option given the performance experienced so far. Intel take note that the impact is now beyond the mere first-person user (me) for this device.
- Wasted weekend, missed quality time with daughter and parents as a result. Annoyed grandparents-in-law. Strong desire to return to pen-and-paper.
- Get back home with device.
Rest happens over the past 2-3 weeks:
- FInd the device isn't activated and it fails to do so.
- incrementally get it to run OK, update OK. Note No sound still.
- Virus scanner, firewall, firefox, chrome installed, running. Even my old wireless Logitech keyboard/mouse (which require a USB dongle...a boon in this case 'cos they work with the recovery/setup/bios as normal USB kbd/mouse). After a while it shows signs of some instability so decide I want sound so...
- ...another fresh install again. NO SOUND on HDMI.
- Reinstall everything (updates, firewall, virus scanner, Firefox, Chrome, even Citrix remote access). All fine, but I do note performance is barely adequate. Still no sound. Note the Intel HD Video (for video) drivers are working.
- Three goes on the phone (once I discover the contact number), two with an actual person and I eventually get it activated (but that's a Microsoft issue).
- SFC, DISM OK.
- Cast around internet. Eventually find some info on possible missing drivers and the audio drivers should be embedded with the video ones. One of particular interest is the Ëmbedded Intel drivers"or similar. Multiple reinstalls of the video drivers does not fix the sound.
Note the issue with the audio drivers is that no audio device is present nor can one be added. the "unknown device" in Device manager exists and can't have the drivers updated or replaced or reinstalled or uninstalled +rescanned.
- Try various downloaded drivers. It becomes a bit unclear here as I didn't keep a track of the packages and in what order, but...
- the intel embedded drives package seems to work I think and I think I ended up with a "Intel WDM Audio driver" listed instead of the "unknown device", although there is still no sound.
- I installed another package (or this one) that causes the Intel HD video drivers to fail. I am required to retreat to safe mode and uninstall or disable the Intel Video Drivers and use the "Microsoft Basic Video Driver" (or similar).
- The video failure here consists of a blank screen (at full display intensity- shown by the grey background, as opposed to a black background) on the display but with the mouse cursor visible! The only solution at this point is a reboot wither through the power button or removal of power on occasion.
- No amount of uninstall/reinstall video drivers fixes this, in fact...
- Upon an install of the Intel drivers (or update to the basic video driver) the screen will flicker and then, after a few goes, exist to a BSOD I haven't seen before, "VIDEO TDR FAILURE" sometimes with igdkmd32lp.sys (but not always)
- Reboots after this result in the grey screen + visible cursor, but no BSOD. I get the impression WIn10 is running but for some reason the image is not being presented to the video driver.
INTERESTINGLY: On ONE of these reinstalls, the computer (under the grey screen ) emitted a "BONG!" error noise that can only have come from the HDMI speakers- so I know audio CAN be installed. But the grey screen... meant a reboot into safe mode for a disabled Intel HD Video and using basic video driver, so no sound...
- I have to run in basic video driver mode and turn off the automatic updates, especially for drivers, so no sound (again).
- FInd I can run OK here, but no sound and (i.e. youtube video and the like) performance is inadequate (basic driver no doubt)
- Run a INtel Processor Diagnostic. All OK. BUMMER- can't blame the hardware!
- So I think I can give this one more go this evening, so I've
Just done a clean reinstall (with saved personal files though) whilst attached to a HDMI TV. It has come back with NO HDMI SOUND.
However I will now keep some sort of log of what I do/install and post back later with the results.
Note of course, this is being typed from another computer...
