E1DA Cosmos ADCiso Review

[torgeirs]

Can you change samplerate when not REW has it in exclusive mode and RME equipment are disconected?

 

[staticV3]

I want to use ASCiso in other contexts than REW and I am not able to change the sample rates in Windows settings.
Also, I’ve been reading about that REW error message and it suggests that I need to change the sample rate in Windows audio settings - which I cannot.

Windows lists all supported sample rates and bit depths properly but I cannot make any changing, I get an error message and I’m stuck on 44.1kHz. That’s with or without Comtrue driver.
For example if I want to change to 48kHz:
View attachment 498111

It’s a bit of a bummer to be stuck at 44.1kHz to say the least.

Usually, you can select everything from 16/44.1 to 32/384 in the Sound Control Panel.

Have you tried plugging your Cosmos into another Windows/macOS/Linux machine?
Does this behavior carry over?

If so, then a hardware/firmware issue is likely.

If not, then it's likely a software/configuration issue.

staticV3, I don't think the issue is related to FW, just because FlexASIO works. Rather, his Windows has some settings to stick the Fs at 44.1
Anyway, he can try to reflash the FW attached.

 

[torgeirs]

The RME driver might make it sticky

 

[torgeirs]

And Windows blame the ADCiso when trying to change windows ADCiso samplerate



Function like a charm if RME samplerate and Jave samplerate match and no fidling with Windows samplerate

 

[torgeirs]

But my balance slider works. Stereo from 0 to 6. RIIA from 7 to 18. Mono from 19 to 100

Deselecting the RME device enables all samplerates .

Thank you guys for your different suggestions.

- I've tried to unplug my RME DAC but same problem.

- On the same PC, I've used an old Windows 10 disk that I kept, booted on that, and everything worked OK, I was able to change the sample rate in Windows options, and the Java Exclusive mode.

So something is not exactly right with my Windows 11 setup.

@IVX thanks for the firmware. Are there any particular changes compared to v13 that we need to know in this v14?

 

[IVX]

yes, I made a priority for the Tweak_Cosmos.exe slide for the MONO/STEREO mode.

 

[melowman]

FWIW : no luck with the v14 firmware.

 

[IVX]

it is software related issue, the ADC is fine..

 

[melowman]

Probably, thanks Ivan.

 

[IVX]

Mine REW 5.40 beta 103 works fine. What is your version?

 

[melowman]

5.40 beta 111

When I added that pin-spdif to the Cosmos ADC FW, no one reported that using it. So, we can see how many users need that.

I will be using the SPDIF capability.
Just to make sure: it’s the SPDIF GPIO that is connected to the MCLK pin, right? Not the Master Clock?

 

[IVX]

Right, but pls check if there is really a SPDIF signal presented. I don't remember, probably I switched it off to keep the noise less.

 

[melowman]

Unfortunately I have no scope to check.

 

[IVX]

ok, try that:

 

[melowman]

Thanks will try as soon as I receive my SPDIF board (in a few days hopefully).

 

[IVX]

What kinda SPDIF-board did you buy? Usually, such boards have I2S input. With Cosmos ADCiso you do need only the optical output(Toslink) part like this:
