As good as ASUS Xonar Essence STX II 7.1 ?

Looking for PCIe with 8 channels, not discontinued, either well accepted Linux software or UAC2

plus updated ASIO drivers for modern windoze
 
Do you have a budget?
You need 8-channel for a 7.1 speaker setup or 7.1 for headphone surround sound?
 
Speakers, but just plain 8ch per card not 7.1

Cheap as possible but ideally SQ better than "good enough"

Going via USB and ADAT format converters, ADC/DAC ports, I've been looking at $15-30 per port. 24/44.1 or 48kHz is fine.
 
Even if it were PCIe, I doubt SQ as good - more like gaming oriented, DSP effects

hardly works as a UAC2 device other than Stereo-only on Linux

The ASUS card, though very old in fact still has excellent kernel / ALSA level support

But yes, X4 has better / official Win11 support

In any case, this thread is asking for PCIe interfacii, not USB based

but thanks!
 
IMO the market for add-on PCI-e 8ch cards is tiny tiny. Onboard HDA codecs are good enough for vast majority of users. As a result almost no PCI-e audio controller chips are available - I know only Creative (soundblasters, unavailable to third-party) and C-Media (Oxygen CMI8xxx chips, C-Media does not release firmware programming docs, will only create and ship the chip firmware themselves). Some of the few newer internal soundcards offerings are USB-based - PCI-e USB adapter chip + USB receiver chip - a clever combination which uses available chips and requires no drivers - but it's a USB audio device, not PCI-e with direct access to the controller DMA memory. Then expensive PCI-e FPGAs - RME (HDSPe, also unavailable to third-party), Dante cards (that's a different technology).

It would be interesting to create a DIY FPGA audio controller, but such FPGA chips are quite expensive

4 Analog Channels: 4 inputs and 4 outputs (using standard XLR connectors)

4 Digital Channels: 4 inputs and 4 outputs (using AES3 or S/PDIF formats).

All 16 streams of audio (8 in and 8 out) can run simultaneously at full 24-bit/192kHz resolution

official, certified Windows 11 drivers, both regular ASIO and Multi-Client both have a great rep

However no Linux/RPi support at all

And NOT cheap, even used
 
Yes, if

1. I knew I would def use it on Linux, never want to run windoze, or

2. I see a crazy cheap offering on a good secondhand platform

But I'd rather spend a bit more on a current / officially supported model that meets my OP requirements
 
With the rise of "good enough" and sometimes even good onboard audio the choices for PCI(e) got slim.

Current PC mainboard layouts also contradict it a little. You usually have PCIe x1 as an option to route via the chipset with all the other stuff. Or populate the 2nd PCIe x16, which then cuts into the 1st x16 performance - unwanted operation if there is a performance GPU. Or you have onboard/CPU graphics and don't care about the 1st PCIe x16.

Of course you can always get a better mainboard/platform, that's just the mainstream.

Cheap, current model, linux support.. quite a wishlist too.

Here is a nice one for the price of a PC: https://www.rme-usa.com/hdspe-aio-pro.html

Sticking around to see if there are more suggestions.

My advice would be to also look into the music production world. External, thunderbolt, what the apple people use..
 
Oh yes I realize the wishlist makes for a challenge! This thread is very specific, narrow on purpose

The "cheap" part in least priority just trying to collect my options in the PCIe subset.

to further clarify, 8x analog channels, that AIO card has so many digital options but not what I'm after.

And yes I am deep into the wide world of pro interfaces, ADAT expansion converters etc.


...

So obviously well aware of the RME product lines as a result and some of the legacy ADC/DAC options are reasonably priced per port secondhand

In fact I've picked up RME Digiface / Multiface expansion breakout boxen super cheap

but these usually come with PCI or Cardbus (requires futzing around)


while the modern PCIe options are usually well over $40 per port just for the card

...

Same with USB interfacii, I almost snagged an RME Digiface USB (32x each I/O channels at standard resolution) for $310 shipped, but not planning on paying $400+ given the cost of decent converters needed on top.


...

Legacy Firewire based stuff is very well priced, but futzing around and limited lifespan.

...

Currently looking at legacy Yamaha processors for keeping PCs out of the signal chain

the Mini-YGDAI card platform gives incredible flexibility and value for money, especially given those processor base frames that offer slots for 4x cards, some 16x channels each.

$10-20 per channel even for analog and AES3, much less for ADAT.

8 analogue out on a 1 slot pcie card is a physical challenge. RCA or 3.5mm - the most I've seen is 7 jacks iirc (creative card).
 
Nothing wrong with 3.5mm per 2ch, the breakout box approach,

or daughterboards as is most common, and as used by RME and the example here, ASUS Xonar Essence STX II 7.1
