The high pass filter section, removes the set frequency and below from the assigned speakers:

This removes bass from the satellite speakers.



The low pass filter section, removes the set frequency and above from the assigned LFE:

This removes all but bass from the LFE.


What is Bass in music and how it affects your music experience?

Use channel factor to increase LFE volume, 1.0 = 100%, 1.5 = 150%.

View attachment 273285

so should I unselect LFE from high pass and select LFE in LOW pass only?
as time of writing I have all channel selected on high pass

 

[Ferather]

Yes, All but LFE in high pass, LFE only in low pass. That's why the bass was wrong, both frequencies should match.

what are recomened setting for 5.1 surround system
current i am using this

Copy: L=L R=R C=0.5*L+0.5*R LFE=0.5*L+0.5*R RL=RL RR=RR SL=0.5*L+0.5*RL SR=0.5*R+0.5*RR

is it right?

 

[Ferather]

I would recommend: LFE=L+R , but that is up to you, if you are happy with 50%-50%. You can remove the side since you only have 6 channels not 8 channels.

To get 8 channels over 6 channels (7.1 over 5.1 system) on analogue, go to the speaker config, set as 7.1, and remove the side.
This tells Windows to handle 8 channel audio over 6 channels, creating virtual sides between front and rear.

so you r recommending

Copy: L=L R=R C=0.25*L+0.25*R LFE=L+R RL=0.5*L+RL RR=0.5*R+RR

am i right?

is DTS sound unbound been fixed? Last i tired the cr**ked one provided it always change my sound to stero...

 

[Ferather]

Its good you are learning how to use E-APO, it can be a little tricky, but has a lot of potential. Here is an edited 5.1 upmixer config:

If: inputChannelCount == 2 or inputChannelCount == 0 << Detect stereo (2 channel audio), ignore multichannel | Change 0 to 6 to force web browsers.
Copy: L=L R=R C=0.25*L+0.25*R LFE=L+R RL=L RR=R << Clone the 2 channel audio into the extra available channels, including LFE.
Channel: L R C RL RR << This is the start of crossover to LFE @ 180 Hz, this config allows for further tweaking.
Filter: ON HPQ Fc 180 Hz Q 1.4 << Change 180 Hz to suit, [removes bass].
Channel: LFE
Filter: ON LPQ Fc 180 Hz Q 1.4 << Change 180 Hz to suit, [bass only].

Sound Unbound is for stereo, that's why it keeps switching, the app is not needed with multichannel.

E-APO SFX Upmixer

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

www.mediafire.com

Stereo to 5.1, SFX only, no MFX or EFX enhancements included in the sample.

 

[ajf64]

The most common crossover frequency recommended (and the THX standard) is 80 Hz. On-wall or Tiny 'satellite' speakers: 150-200 Hz. Small center, surround, bookshelf: 100-120 Hz. Mid-size center, surround, bookshelf: 80-100 Hz.

 

[Ferather]

I prefer full range bass from my LFE, but that's a personal preference, I feel 80hz is too restricted.

Some of you might get Realtek updates from Microsoft updates, see here to disable it. In my case I don't bother as Windows never finds an update.
If you are using third party apps, they might have another source of files and also try to update (replace) the driver.

You can also download this microsoft troubleshooter to hide just the Realtek updates and keep receiving updates for the other devices installed: https://download.microsoft.com/down...9CD-4275-8C95-1BE17BF70B21/wushowhide.diagcab

 

[druboo_666]

if i enable stereo mix it interrupts with pc sleep cycle and as a result my PC never goes to sleep.if i disable stereo mix its stops interrupting with sleep cycle and i think it will go to sleep now.
i inquiry this with windows power cfg command.
here are r screen shot of before after disabling the stereo mix

any solution other than what i have achieved?

 

[Ferather]

You only need stereo mix for SPDIF when using an encoder, you don't need it for speakers. It makes the encoder always on and connected to the receiver.

so i should disable it?

 

[Ferather]

Yes, you don't need it for speakers, especially if you want the power save.

 

[Ferather]

A few members have asked if this driver will work with S1220A, the answer is it will work on any Realtek device that is HDA, in short everything but the USB versions.

Currently I have an Asus Prime X570 Pro with S1220A.

 

[druboo_666]

@Ferather
in high pass channel should i select L & R also (if i select those channel that removes the bass) or should i select only C,RR,RL
i have 5.1 analogue audio

 

[ajf64]

I prefer full range bass from my LFE, but that's a personal preference, I feel 80hz is too restricted.

i feel you all audio is really personal preference most people with small speaker systems tend to be really restricted and most subs don't go below 40hz so the range seems compressed also small speakers usally have almost no low end so they need the sub to provide any sort of bass above the crossover point so they set it higher. With a good sub that drops to 30-20hz 80 can sound alot better since you get much clearer mid range and highs its really a shame how handicapped mid range and lower cost sound systems are what made the z906 so impressive if they had put an hdmi port on that it would still be one of the best systems you can buy period. Also the z906 if you use the built in amp will always be 80hz cross over cuz since thx specs are set in hardware they did not provide a way to change the crossover frequency like other subs that cost more even if you set it higher or lower in software the amp will pretty much ignore it tho you might lose some other frequency on other speakers that may cause a sound change that could sound like it was working or doing something need a sound meter to measure the swap

 

[Ferather]

@druboo_666

If you select L & R, any enhancers for bass on MFX or EFX (both after SFX) will not work as the bass is removed, normally the bass is removed from all channels, and the LFE gain balanced.

----

@ajf64

Interesting, if I increase the crossover frequency (SFX), which is pre Z906, it removes bass from the satellites and instead added to the LFE unit, that being said I have the original.
The current model is visibly slightly different to mine, although the specs on the site have not changed, I am not really sure there is a difference.

Still, everyone ears and receiving speakers are different, change the values to suit.

----

Given some customer ear bending perhaps Logitech will be the first to update SPDIF to the current consumer standard (15 channels, all formats).

 

[ajf64]

it will remove the bass from satilites but have you messured the cross over frequency from the sub its self and not software from the readings from mine it would not go above or below 80hz but there is always the chance im wrong i do have the most recent revision so that could be a factor i have a sub with a cross over switch will do 60,80 and 120 so i tested vs that

 

[Ferather]

If you want to test 5.1 audio on SPDIF after installing the driver check here: AAC Multichannel Playback Test (fraunhofer.de). If its a game set it to 5.1, or in some cases speakers.
Some games are stereo only, and some games are stereo but connect as multichannel (like web browsers), use E-APO to upmix stereo, and force upmix, to 5.1.

@Ferather
DTS:X Ultra always resets for stereo every time i restart my pc until i reconfigure it from realtek audio panel.
and this is before configuring it

Spoiler

this is after reconfiguring it from realtek audio panel

Spoiler

IS this behavior normal?

 

[Ferather]

No it isn't, sorry for the late response. DTS reads a registry key to determine stereo or multichannel, I am not sure why the key would change to stereo after a restart.
This is the first time I seen this issue. I can only guess somehow something is changing it from multichannel to stereo.

How can I trouble shoot to fix the issues
also which reg to merge for analogue multichannel?

 

[Ferather]

No reg merge for analogue, that's for digital since it has no speaker config option (or to expand DTS to HDMI). Below is a screenshot of my optical output (in your case it would be speakers).
I have highlighted the two keys that control total channels available and total channels output (in this case process 8 channel audio for 6 speakers).

I would also check for any other audio apps, it almost sounds like an app is starting with Windows and changing it to stereo.
If you have Sound Unbound installed, try removing it and see if it still changes after a restart.



Use 'FX Config' to open regedit on the device (right panel).

can you help me to solve problem via team viewer or anything when you r free to do that

 

[ajf64]

@Ferather so small update i built a new pc i got a 7950x with gigabyte Aorus x670e Xtreme motherboard that comes with an ALC1220 but this 1220 only has a spidif port no analog 5.1 so they just copied you and added dts ultra to interactive over spidif to improve audio quality you need to tell them they owe you money lol. Have not used it yet since im on HDMI but i got a suspicion that yours sounds better
