DISCLAIMER: It is now 5AM and I've had about 8 hours of sleep over the past 48 hours so I might be imagining things. I'm pretty sure there is a difference in audio quality, but without 2 phones side by side, it's hard to compare

Instructions:
1) Flash any DesireHD ROM, your choice!
2) Flash the attached zip file with CWM (it includes the Inspire 4G kernel)
3) Install the attached PropEditor apk, and run it.
4) Open build.prop using PropEditor and change

Code:
htc.audio.hac.enable=0
to

Code:
htc.audio.hac.enable=1
5) Hit the menu button and save! REBOOT!! win?


Let me know how it goes! I do hope I'm not going crazy


I'll update tomorrow with what exactly I did. Too tired to type it out now, GOODNIGHT.

THE DIFFERENT VERSIONS:
-V2: Better quality than V3, speakerphone microphone does not work
-V3-test: Slightly worse quality than V2, better than no sound fix, speakerphone microphone works 100%

CHANGELOG:
V3-test: Removed extra files, sound quality is around the same (or slightly worse) compared to V2. Speakerphone Mic should work

V2: Removed AIC3254_REG_DualMic_MCLK.csv and AIC3254_REG_DualMic.csv as suggested by BelacNongaw to fix mic

Although still not perfect, its 10x better than before with the telus. Unless I forgot the quality of stock which could be possible. But there is definitely a huge difference, to the point that I'm not going back to telus. Good work! Plus, the stock source kernel is being used which is always the best for stability eventhough telus didn't cause any stability problems.

Exception to my last post, it actually did fix everything! Audio in media player sounds as it should, ringtones sound perfect, etc. This thing is now perfect! Dhd roms, using stock kernel with perfect audio, themes, root access in less than a week! I love xda!

Could unrooted people use that apk to enable hsupa in the build.prop? I'm curious....

Well I'd have to compare the stock build.prop to the DHD one that people have installed, but there are these values in the DHD one:

ro.ril.enable.dtm = 1
ro.ril.gprsclass = 12
ro.ril.hsdpa.category = 10
ro.ril.hsupa.category = 6
ro.ril.hsxpa = 3

Guessing one of those is changed in the stock. Will check later

EDIT: Just pulled the build.prop off my unrooted phone and they look the same... odd

failed to remount system rw
I keep getting an error when trying to save build.prop after editing. "failed to remount system rw". I tried creating a backup and editing that then restoring it but got the same error. Am I missing something simple?...lol...thanks

I've been working on this too. Remove AIC3254_REG_DualMic_MCLK.csv and AIC3254_REG_DualMic.csv from /system/etc/ in the zip and this will work without breaking the mic. Good job.
