Looking for a 192 KHz sound card supported in Linux

Hi all,
I am new to ardour and would like to give it a shot editing
files at 192 KHz. But not all 192 KHz soundcards have Linux
drivers. Has someone used a 192 KHz card under Linux with ardour
or has heard of such a card supported under Linux.

I have no direct experience (yet), but I have heard only good things about RME Audio and their support for Linux. I just checked their website and see that they have a very recent mention of Linux support for their latest HDSP AES-32 card: http://www.rme-audio.de/en_downloads_driver_archive.php

Obviously that card is a digital audio I/O card, so you still need D/A to hear the result, and you’d need an A/D if you want to record at 192kHz. An 8-channel I/O 192kHz converter is something like an ADI-8 QS (see http://www.rme-audio.de/en_products_adi_8_qs.php )


i have a ESI Juli@. This interface is able to handle 192 KHz.

It is mostly supported, just the midi input is killing my system. if you disable this, that could be a card for you.

Thanks a lot for the hints.

i have a firewire device (edirol fa-66) which supports it too

I have the FA-101, which is great and works well with freebob drivers. I can’t get the latency below about 8 ms without huge artifact problems though, which I can do on OSX.

same here - I have it at 10ms with a 96000hz samplerate but when I try to go lower it gets hard not to get xruns

I have been monitoring VLF signals on and off since the 70s.
Back then it was L-C tunes circuits, opamps, and a chart
recorder. Now it is a modified Gnuradio on Linux receiving
and logging a handful of signals at once. (sww www.omen.com)

This is a good test of A/D conversion. The first setup coupled
my loop antennas to the CD input on an ECS NFORCE6m-a motherboard.
This could sample at 96 or 192, 16 or 24. It just worked!

Unfortunately the motherboard has limited SATA storage, so I tried
other motherboards. The ones I’ve tried had intermodulation
and/or noise problems. I am currently using a Gigagyte board
but it needs a preamp to work. Even with the preamp it doesn’t
seem to work as well as the NFORCE6m-a board.

The NFORCE6M-a board has an IDT 92hd202 codec and low noise
in the ultrasonic range. This superior signal reception may
or may not translate to superior audio, but it can’t hurt.

This motherboard may be hard to get but may be worth it.
The cards I’ve seen mentioned with this codec cost hundreds.

Hi there, and hello to everyone,

Sorry for bumping an old thread, but I am a newbie to homerecording and currently considering buying this card. Therefore I would like to know, if the problem with MIDI freezing or killing the system still remains.

I am on Slackware64-current with kernel, but would be ready to use a specialised distro, such as JAD, as well, if necessary.

So, is MIDI working now with the ESI Juli@, or is this still a problem?

Thanks in advance!



Midi works for me now with the 2.6.32 kernel.


Thanks for the immediate response, good news, indeed!

From your other contributions to Ardour forums I can see that you have been using the Juli@ quite a while now. Would you still recommend it, or would you prefer something else, today? Is it/are the drivers stable?

Thanks again!


All modern RME converters can be used with RME’s MADI or AES interface on linux and do 192kHz without any hassle.

Point is, though, why do want to work witj 192kHz? For audio application targeting humans it makes no sense. When doing real time processing, it might make sense since the conversion latencies are almost NIL (7 samples). I know of a few appliances, e.g. monitoring gas turbines or airport runways.

Unless your customer pays you to deliver 192kHz, I would suggest you stick with 48kHz and instead invest in decent converters.

Thanks, faberman. If my budget would allow me to do so, I’d choose RME products — no question about that.
Also, I understand your point regarding 192 kHz, and after researching a bit further, I guess, you are quite right. Nevertheless: The ESI Juli@ has this capability plus symmetric jacks at an affordable price. It’s therefore sill on my shortlist, but I’d like to make sure, that it is stable and fully supported in Linux. The converters are reported to be excellent.

The other options are all members of the M-Audio Delta series: Audiophile 2492, 1010LT and 1010 (with the last one possibly being overkill for my initial needs).

While it is easy to get information about the M-Audio devices, I’d like to hear a little more about the ESI Juli@ from users who own it. Would you buy it again, today, or would you recommend something different, and why?


With the actual drivers, I would buy it again.

The analog in/outputs are working, as well as the midi io’s. I just didn’t managed to get the analog io’s working with the spdif io’s, but that should just be a matter of time and .asoundrc knowledge.

Just my 2 cent,

Sounds good. Regarding the SPDIF thing you mention: Do I understand you correctly, that it is a configuration issue, not a driver support issue?


As i see this, yes.

I tried just the analog io’s, so I can’t tell you much about the SPDIF io’s. But I read reports that they are working, too.

So everything left is to combine both io’s to make them work simultaneously in Jack.


Could you provide an URL to these reports on working SPDIF?
With my favourite search engine I can’t find them…



sorry for the long delay, I was pretty busy.

But here you can find a discussion in the alsa mailing list, which indicates spdif to work:


Thanks, then it’s the Juli@!

Everything seems to be supported now, or in the foreseeable future (in ALSA 1.21 there seems to be a bug, fixed in GIT, according to J. Kysela).

Although some other members here question the need for 192 kHz, I don’t see any disadvantage of the Juli@ even in case I find, that 96 kHz or less is good enough for my purposes. I don’t see a better audio card at this price with symmetric jacks.

So thanks for sharing your experience, very helpful!
