Hi,

Sorry but i dont understand one thing... On my old PC i´ve got sound card ASUS XONAR DG (only for 30 euro). My headphones are Sennheiser HD518 with 50 Ohm. When i compare sound on ASUS sound card and on my new PC motherboard asrock z170 fatality gaming k6, ASUS absolutelly wins. Sound on my MB is sooo baaad. I mean bass isnt so deep, all the sound is like I was sitting in a canister. I change my equalizer as like on my old sound card but there is still very bad sound. I dont know how it is possible because that sound should be very good but its not. It sounds like my sound card goes only on 32 Ohm... idk... Can you help me? Is that possible that i have some wrong options ? Maybe something disabled in bios? Or is that very true that i buy expensive card with horrible sound? Thank you very much....

The TI® NE5532 Premium Headset Amplifier on your board should be able to drive your 50 ohm headphones fine. They only need 1V RMS for 108 db output.

Any PC normally has multiple audio sources, and the one you want to use may not be the default audio device. Audio sources in a PC include the Intel Z170 chipset, the audio from a video card, and the special audio chips on the mother board itself, added by the board's manufacture.

In the Window's (what version are you using?) Sound settings in Control Panel, be sure you are selecting the board's audio chip (Realtek ALC1150), and have the Realtek driver/software installed.

There is usually more than one level or volume control setting in Windows, be sure they are all set high enough.

Where are you connecting your headphones on the PC? This is really my main question, since setting up a headphone output takes some configuration of a cable to the front panel audio jacks, and of the software that your board uses. It may not be configured for stereo, but for multi-channel sound, and the bass frequencies are not being sent to the headphone output.

Im using Windows 10 PRO 64-bit. In sound control i have 2 sources = Speakers (Realtek HD audio) and Realtek Digital Output (Realtek HD audio). When i click on Speaker preferences there are 4 types of connectors (green, pink, blue, orange) and when i click on Realtek Digital Output there is only one connector (black = Optical) 

My headphones are connected in rear panel, in to green jack = Front speaker. I dont use front panel on my case. I read MB manual and I shoudl connect my headphones right there (rear panel - green jack).

I also try setup my Realtek sound manager. I see some video on youtube, setup it like on video but effect is still the same.

If you want i can do some printscreens, just type exactly what settings and i can do it....

Same for me. Coming from a Xonar D2 (no headphone amp), the onboard sound is worse and volume is too low. Can someone confirm if the headphone amp from Asrock's purity sound 3 works with the rear panel audio jack (or is it only for the front panel audio jack) ?

Although we don't know what board you have, if you install the Realtek audio driver package on a board that has the Purity sound feature (as my ASRock Z170 board does), and run the Realtek HD Audio Manager program listed in Control Panel, you'll find the headphone output is on the front panel audio connections.

Of course the icon in the Audio Manager software for the front panel headphone output won't appear unless you have a cable from the PC case connected to the HD audio header on the mother board.

The rear IO panel's Front speaker outputs are not meant to be used with headphones. Or more specifically, a standard audio preamp output (which is what we have on the rear IO panel "speaker" outputs. They are really outputs for driving audio amplifiers that will then drive speakers) is not meant to drive a low impedance device like modern headphones. None of the speaker outputs on the IO panel can drive low impedance headphones.

A standard torture test for audio pre-amplifiers is to have them drive a low impedance, 600 Ohm load. That is very difficult for a pre-amplifier that is designed to work with devices whose input impedance is at least 10,000 Ohms, and should be higher, the higher the better. The usual result in such a test is the bass frequencies are rolled off (reduced in level relative to the midrange) below 100Hz, distortion is higher, and the output voltage level is reduced. That is exactly what you are all describing.

Home audio pre-amplifiers have separate headphone outputs, which are designed to drive low impedance loads/devices like headphones. Why would we expect PC audio to be any different?

The idea that a "speaker" (actually pre-amplifier) output on a modern PC mother board can drive low impedance headphones is simply wrong. I doubt that any manual said the speaker output on the IO panel is compatible with low impedance headphones.
