Due to the 'Access Denied' glitch on this forum (search on 'Access Denied'), seemingly afflicting new thread posts which use more than one paragraph, and similarly replies, as a work-around I'm kicking this thread off with this, and getting down to business with my 'replies', below. At least that's the idea...
Nope, can't post or reply with more than one paragraph. I'm attaching a screenshot to this reply which at least displays the basic issue, but not the steps I've taken to try to sort it (and failed). (Just previewed my 'reply': at least the image is going through.)
So here's my original post in sections as 'replies' :mad:: As per the title, I no longer can record using 'Line-in', 'Microphone' and 'What U Hear': all are showing in 'Sound' (see pic) as "currently unavailable" (OR, as has recently happened, the "What U Hear" shows as "Ready" but in practice doesn't function when using recording software...) These options were working for years, up until a while ago. OS is Windows 10, updated, no particular issues.
So: Uninstalled the Audigy's drivers (using Revo Uninstaller, as Creative's uninstall file mysteriously missing :mad:) and reinstalled latest: no change. Bought and installed a new Audigy Rx: reinstalled drivers from CD: no change.
So: Reformatted C drive*, reinstalled Windows 10, reinstalled the sound card drivers before any other software or updates (*after making an image of the C drive using Acronis True Image, so I could simply revert to it. I also saved an image of the new basic install, so i can go back to that too). No change: both 'Line-in' and 'What U Hear' still showing as "currently unavailable".
So: Given that the sound card's apparently not the issue, and it's not an OS conflict with some other program, I had a look around the BIOS but couldn't see any setting that may be responsible. The only other cause I could think of is that I recently updated the mobo's firmware (from the BIOS using Asus's EZ Flash, to 1207 x64, dated 22 June 2018).
So: We have another PC with the same model motherboard. The BIOS on that one hasn't been updated (it's 1804 x64, dated 7 June 2016). I installed the new Audigy Rx on that. Same issue: 'Line-in' and 'What U Hear' showing as "currently unavailable"!
So: as far as I can see, this 'coincidental' glitch isn't down to: a BIOS update, software conflict, a faulty soundcard, a faulty motherboard, or a Windows update (when I reinstalled W10 I didn't allow it to update, and I don't think one was performed during installation).
