Hello again,

So I turned my htpc into a gaming rig and switched out my AsRock mobo for the Z87I-Deluxe and the i5-4670K. I noticed that while watching movies on XBMC the bass was super weak. I thought it might have been the subwoofer because I had it repaired due to a faulty board. But after testing games on the Xbox 360 and PS3 (plus movies on PS3) the bass was working and sounding great. I have a Onkyo HT-R592 receiver and it worked perfectly with XBMC and my previous mobo. No with this new mobo it puts out weak bass. Could it be my GTX 770? I'm lost. Much help would be appreciated.

My current rig (don't know if this helps):
ASUS Z87I-Deluxe Motherboard
Cooler Master Seidon 120M Liquid Cooler
EVGA 600B 600W PSU (100-B1-0600-KR)
Gygabite GTX 770 (GV-N770OC-4GD)
Intel i5-4670K 3.4GHz CPU
Kingston HyperX DDR3 8 GB
LG UH12NS30 Bluray Drive
Lian-Li PC-Q08B Case
Seagate 600 Series 240GB SSD (ST240HM000)
3 x Seagate Backup Plus 4 TB
Windows 7 Professional 64 bit OS
 
ok... not totally up on what you are asking since I do not know what speaker system you are driving.. Is the sub self powered?

I run my sound out my GPU's HDMI to a Sony Home Theater system (shows up as a 3rd monitor on the GPU)

How are you driving it?
 
If anything it would be the motherboard, I mean that's where you plugged your audio connectors into right?
Is the volume lower overall comparing to the older setup? or is it just the bass only?
Try reinstalling your audio driver and update it to the latest version, if you have optical audio input somewhere on your speaker system then you can try that, or an adapter from optical to composite would work too. In addition, you can try a different speaker, perhaps a headphone with good bass.

I have an Onkyo HT-S5600 7.1 Surround Sound System. The sub is self powered (plugs into power outlet and an RCA cable to receiver). I have an HDMI connected to the GPU then to the receiver and it goes out from there to my projector. Sorry hope that clarifies it. I am not running any additional software for my set up other than XBMC (audio output device and pass-through set to WASAPI: HDMI-HT-R592)

It's picking up everything. It picks up 7.1 speakers, HD audio formats (Displays them on the receiver), the only thing is that the bass output is super low. I didn't change any of the sound settings on the receiver between hardware upgrades on my HTPC. When I play a movie it plays fine, I get surround sound, but the bass output is weak. I crank it up all the way to get descent bass. If I switch over to the PS3 or 360 the bass works as it should. I have to dial it down after switching from PC to the other peripherals.

The realtek audio control panel only allows me to change settings if its hooked up via toslink (optical audio) or aux inputs on the mobo. It won't let me adjust sound through HDMI.

I did as you advised. I uninstalled ALL the Nvidia drivers, restarted PC, reinstalled drivers (clean install deleting any profiles), and tested movies with VLC, PowerDVD, and XBMC. All resulted with low bass output. I switched over to the PS3, played Infamous and got booming bass. I am at a loss :/ I didn't have this issue with my ASrock mobo :(
 
I hope this post can help you, as you probably can tell that I don't know much about audio, so I don't even understand what they are talking about half of the time. Good luck reading it, I hope it will help solving your problem and that you understand the different possibility to solve your issue, not just the final solution for him.

I'll give it a read but I'm not trying to get bass through stereo but rather stronger signal from 7.1 set up. I'll give it a go (I did run into these threads though).
