I tried plugging the Antlion ModMic into the ‘mic’ input at the back of the mobo (Sabertooth TUF X99), no signal in OBS. Front-panel connector, works but I have horrid noise floor. Compensating by adding -3dB of noise cancellation in OBS… (mine’s more an audio input issue here).
Can’t use my Focusrite Scarlet interface as the Antlion needs a 9-12vdc voltage vs the Scarlet providing 48vdc phantom power. I could solder up a solution, but then I’d need to grab another wall-wart and throw in some 12vdc regulation circuitry (which I’ve done for my home-made DIY lab power-supplies); just can’t be arsed to do so LOL.
Let us know on how you figure out the cause on your Taichi…
I have an Asrock X399 Taichi that uses the same ALC1220. I’m running ubuntu 16.04 and have crackling issues with my microphone. The output is good though.
9-12v sounds high. an electret mic element usually only needs 3.5-5v. dc power from a pc mic socket is usually in that lower range
try a battery instead of mains power. very simple and no mains noise problems. you should probably add a capacitor to block dc power heading toward your interface, but the focusrite is likely to block it anyway
If the modmic can cope with a higher voltage than already supplied from pc you might get improved sound quality
Just an update for anyone who’s encountering similar issues, I finally got around to RMAing the motherboard. Swapped it out, updated UEFI, booted up and I’ve got no problems now!
Apparently it was a motherboard defect. Thanks Newegg for the Advance RMA!
Just FYI, I had the same issue with an Asrock X399 Taichi, just missed this thread because I was out of the country when you posted it. Curiously enough, also on the left channel. I ‘fixed’ it by remapping line out to another port using a fake firmware file.
I distro-hop too much for that to be a reasonable solution. I still have to send it back, but I wonder if there was a bad batch of one of the sound components.
You’ll be happy to hear that the RMA was as easy as calling them up and saying that the left audio channel is broken and asking for an advance RMA.
Alright, update: I just tried applying the overclock and realized that I can’t get my 1700 to 3.7GHz (other board was happy at 3.8) at the same time as running my memory at it’s rated speed of 3200mhz.
Additionally, I’m unable to see one of my m.2 devices. I think I was sent a bad board. Reinstalling the original taichi and will report back if the deadlines I’m missing don’t kill me.
UEFI is updated.
UPDATE: Just got the motherboard installed. Looks like I’ve damaged my CPU. I’m beyond furious right now. I guess I’m going to Frys first thing tomorrow.
Yeah, Amazon has agreed to replace the CPU, getting one delivered today, so I’ll see how that goes. I just don’t want to kill another CPU by putting it in a bad motherboard. (I also get nervous when using PGA CPUs after being on intel since LGA775)
There’s a similar issue to this except it’s caused by a still mysterious pulseaudio timing glitch on Linux.
Usually resolved by restarting the pulseaudio service, so it’s not always a Hardware defect.
The most frustrating thing is that I’ve got to build 4 openstack images by friday and I only have a u-code mobile system to do that on now that the Ryzen is dead.
