Horrible sound - Prodesk 400 G4 w/ Conexant HD Audio
09-27-2017 05:53 AM

Hi, I just purchased a Prodesk 400 G4 and I am appalled with the sound quality. No bass, distorted sounds and a very thinny tone.
I purchased this to replace a 10 year (yes, ten YEARS) old PC with an onboard soundcard and it sounded great. I don't understand this and refuse to admit this is a hardware problem.
Things I tried:
Checked cables and speakers
Checked if I was using the correct 3,5 output jack connector (and not the input one)
Updated Windows
Updated Drivers (from HP and from Conexant's website)
Disabling the audio enhancements on the Controller's properties/options
Disabling the Multiple Transmission on the HP Audio Controls
Using headphones, different speakers, internal Prodesk speaker and my Samsung monitor's speakers, all to the same horrible results.
Please help me, I use this as a audio/mediacenter and I am not happy with this at all.
Thank you in advance

I have it worked as follow:
-> open Windows 10 Device Manager
-> find the Conexant HD Audio and update the driver through "search on the internet for a driver".
-> this installs currently 8.65.225.0 dated 8/8/2017
-> reboot the pc
Then right click the audio icon in the taskbar (next to the clock):
-> choose the "recording devices" (yes!)
-> select the "stereo mix" device
-> enable this device (disabled by default)
-> set it as default
This seems to be working over here... even after some reboots. Good luck.
