[AT&T, Rogers HTC One X, Telstra One XL] Poetique:
You know... I never really considered it might be a kernel/voltage issue, but my "back" button does occasionally become unresponsive. My home button and recent apps button are the only ones that always work lol.

I actually just downgraded my touchscreen firmware to see if it fixes the issue. Went ahead and downgraded to TWRP 2.3.3.0 as well... I must say, life outside of teal is nice :D

Edit: Also, question about Button Light Notifications (BLN) before I bother with it...

I noticed it said that it works in tandem with the LED notification. Does that mean that if I have the LED notification disabled for certain notifications that it'll also disable the BLN for those same notifications?

Also... does S2U (Sweep to Unlock) work for anyone? I really can't recall it having worked for me since "upgrading" to JellyBean but I honestly havn't bothered much to try to figure out why it doesn't. I'm on Viper 3.2.7, and yes, it's enabled.

Edit 2: Made an interesting discovery on the audio crackling issue... it IS the voltage... sometimes. And the frequency is the problem when it's not. More importantly, it's the voltage at lower frequencies. To be more specific, middling frequencies. Just for a laugh, I decided to set my governor to "performance" to see if the issue occurred. Sure enough, it didn't (due to the fact that the performance governor constantly forces max frequency and thusly, max voltage). So the voltage at max frequency ain't the issue. Of course, neither is the voltage on the bottom end seeing as the video player takes more than the minimal amount of juice to operate properly, and the fact that my device is definitely stable below 900mV with the exception of this one specific issue. Now I'm gonna have to sit and figure out at what voltages/frequencies there is a problem and try to correct them. Which in itself will be a problem, because I know for a fact Viper likes to occasionally randomly reset my voltage frequencies when I set them through Venom Tweaks for whatever reason. Might have to use a 3rd party app to do it, but meh... we'll see where this goes.

I also went in and undervolted 900->850 and noticed that, as long as it's at max frequency, there's no voltage issue. Gonna reflash at 850 and see where my voltage actually needs to be at max frequency for this problem not to occur. With any luck, I'll have my One XL all the way down to 800mV and stable by the end of the day >=) (Ok that's a stretch, but I bet I can pull off 825 for sure)

Edit 3: Presently sitting at 800mV. Max frequency 1250. No audio issues whatsoever at max frequency. I'm pretty sure my device is unstable at this voltage when pushed, so I'm gonna run some benchmarks to see if I can force it to reboot.

Edit 4: Ran a few benchmarks, can't seem to force a reboot @ 800mV. So I went and used Venom Tweaks to undervolt to 750mV... no audio issues when performance governor is used, and still no reboots from benching (without performance being used, of course). Just gonna let it run for a while at this voltage and see how long it takes to cause itself an issue. Oddly enough... I'm also benching higher than I usually do, for whatever that's worth. There's no way my device ought to actually be running stable AT ALL at 750mV, right? o.O Even tried running benchmarks with the "powersave" governor at 750mV (which should force the CPU to the lowest frequency [192MHz]) and managed to get it to benchmark softwares to run, although, Antutu couldn't even sort of complete, and Quadrant wouldn't give me a result after completing. Mild graphical issues appeared, but the device more or less will "just work" at 750. After I figure that out I'm gonna see if I can use Venom Tweak's Max CPU Freq slider to see the PRECISE frequency at which the voltage actually needs bumping.
