Hi everyone!


I have an Auzentech HomeTheater HD  (modded with AD797 OPAMPs for front and OPA1602 for surround speakers).

I run this card in 7.1 mode with a Razer Tiamat 7.1 headset.

All was working well, but some days ago, the side left speaker stopped working. The channel runs on very low volume, even if I set it to 100%.


Did i damage the PCB? Did I damage some electrolytic caps? I removed the stock OPAMPs with a very small heat gun (designed for soldering).


Some things I have checked:

- change volume in Windows

- change volume on headset

- change 3.5mm plug (connected side speakers to front plug, works. connected front speakers to side plug, side left doesn't work)

- repaired headset some weeks ago because of broken cable, excessively tested, all working

- resoldered OPAMPs

- changed OPAMPs (all new)


System specs:

- Intel Core i7-3930K @ 4.4 GHz

- ASRock X79 Extreme4

- 16 GB G.Skill 2133 MHz RAM

- 2x Samsung SSD 840 Pro 256 GB in RAID-0

- 2x WD Black 500 GB in RAID-0

- Teac BluRay Drive

- Auzentech X-Fi HomeTheater HD

- 2x Gigabyte Radeon R9 280X in CrossFireX

- Club3D Geforce GT 640 (for PhysX Hibridiz)

- beQuet! Dark Power 10 Pro 1000W PSU

- SilverStone Raven RV-02 case

- Noctua NH-D14 SE2011 CPU cooler

- Windows 8.1 Pro (reinstalled about one week ago)

- only newest drivers installed

- Steam,, Origin, uPlay and AMD Gaming Evolved App installed

- PAX drivers V1.00 2013 (Auzentech series)


Thanks in advance,
