Not really (because the last days I use the NUC with OpenELEC booting from SD-Card if I want to use it to enjoy videowatching)… but I have to say, I didn’t tested with the newest Intel® HD driver (at the German downloadcenter the 184.108.40.20624 https://downloadcenter.intel.com/de/product/89190/Intel-NUC-Kit-NUC6i5SYH)... I’m actual at 220.127.116.1152
- ChipSet is already 10.1.1.9 (at the German downloadcenter meanwhile they are at 10.1.1.14 but I think the part for this nuc is the same)
- Realtek is 18.104.22.16873 and not 22.214.171.12430 (but I use HDMI for audio)
But it seems to be a resolution / Hz problem that force the damage of audio (missing the audio-device). I use it at the past at 720P/60Hz instead of 1080P/60Hz because I use VNC to manage the device if I don’t use OpenELEC, but it seems if i switched back to 1080p it seems that this foreced the audio problem…
Yesterday I found a little bit time to play a little bit with MPC-HC (Media Player Classic - Home Cinema) and there e.g. with the automatic resolution / Hz switching and I lose the audio while it switched from 1080P/60Hz to 1080P/25 or 50Hz (because of a 25Hz video)… back to 1080P/60Hz the audio was back (found the missing audio-device)…
I will test it with the newer Intel® HD driver and will have a deeper look at it, if I will find time for it (normally I hoped this NUC will be a plug&play device and not a plug&PRAY device which waste my time)… but I have to say the tested 25Hz video stutters a lot at the actual 126.96.36.19924 at W7 while it plays fine at the ‘OpenELEC 6.0.3 with fritsch 98-Intel_EGL’ by MattDevo…
We will see…
The 188.8.131.5224 seems to fix the problem (update via 'Intel® Driver Update Utility' http://www.intel.com/content/www/us/en/support/detect.html?iid=dc_iduu )…
I say ‘seems’ because I only tested two / three times with the 25Hz file switching to 50Hz with MPC-HC and I didn’t lost the audio-device and it also doesn’t stutter…
BUT switching 23.976 to 24 or 23 (both results in/at 24 at Samsung TV) stutters a lot (nearly every 1-2 seconds) but also no lost of the audio-device…
only FYI I also updated to UEFI 0042...
Neither switching resolution nor switching refresh rate (Hz) fix the problem...
At the device manager at 'Audio, Video and Game' the "Intel(R) Display-Audio" is shown as without any errors (I'm not at English but at German "Das Gerät funktioniert einwandfrei")...
BUT then I found out, that the audio was disabled and not "No audio device found"... I can't remember that I disabled it, but maybe I disabled it (or because of the action above and/or restart the NUC it changed to disabled)... so I have to monitor it... if it will be disabled or "No audio device found" again, I will post again...
Hi Hausmeister, I had audio problem appr. 2 months ago, when audio was completely OFF/silence in speakers even everything looks well in Windows. Realtek audio has been started OK (with it's yellow-red" icon in taskbar. I checked device manager - everything OK. But no sound. I allways used reboot and after reboot audio was ok. I solved whole issue by preventing Realtek graphic audio application from start by deleting it's run command from registry : HKLM/SOFTWARE/Microsoft/Windows/CurrentVersion/Run . So I deleted it and since that time I had no problem with audio. Realtek audio app isn't started and I see in taskbar only classic Windows volume icon. I don't know if this can help you somehow...maybe not
