X6000 Out of stock everywhere?

[brsanko]

I've been locked up for a while so the whole Raspberry Pi world is new to me but I just found this online and was super excited Raspberry Pi Expansion Board till I noticed everyone seems to be out of stock. Anybody know where I can find one?

This looks the same: SUPTRONICS ST6000K DAC ES9023x4 HDMI 24Bit / 192kHz 4X 2CH pour Raspberry Pi - Audiophonics

Yes it does, thank you. Not sure how much it costs to ship to the states, though. Whoa, I just realized my account says I'm in Israel. I'll have to figure out how to change that. I've actually been using this site since 2003 or so, but I lost my log in information and my old email address, so I look like a newbie.

Okay, you’re back in the States I see. The Mods will have a look.
Edit: I have removed you from moderation to start.

Found it:
Does the member name brsanko mean anything?
Try again with that. If it works, I will merge this new account into your old one. Let me know right here.

 

[brsanko]

Yeah that's me but I don't have the email address or password or anything.

 

[brsanko]

okay tthat worked Ill just update my profile then.

 

[Cal Weldon]

I can give you the email addy if you want to take a stab at the password.
If not we can merge the old account into the new.

EDIT: looks like all is well. When you are sure, send me a PM and I will delete these extra posts.

 

[brsanko]

Well I figured out the password but I can't seem to figure out how to edit some of the details. Like that picture of thatr guy with hair.

After you have finished I will fix the rest of the things including merging the accounts. I will do that tomorrow. Just send me another PM when you are satisfied.

Just noticed this post. there are apparently two different versions of the X6000 that look the same. One is 7.1 out or 8 channel out , the other is 4 x 2 Ch out.

 

[phofman]

Alsa route plugin can change any channel configuration.

 

[CharlieLaub]

I think the 4x2 configuration is baked into the hardware on that version.

 

[phofman]

IIUC the 4 x 2ch should generate 4 stereo alsa devices which can be merged to a single 8ch device by the route plugin. Timing should be synchronous, it's one serial data channel. But there can be a slight delay between each pair, maybe.

 

[al2002]

That assumes that the 4 channels are not hardwired in parallel. Does anyone have the 4 x 2 Ch card, and can they check?

From what I understand, whatever is interfacing with HDMI on the HAT exposes only 2 channels of audio. These are then "copied" to the four onboard DACs. Sorry that this is a very naive understanding of the hardware, but this is why, as I understand it, you can only access two channels with this version of the board. I was never clear why the designer made it that way and what the intended use was supposed to be.

 

[phofman]

That would be a very stupid design, why wasting the extra 3 stereo dacs?

I know next to nothing about HDMI, but the EP91A6SX HDMI repeater supports HDMI 2.0 which in turn supports up to 4 audio streams. Perhaps the chip in the 4x2 version is configured to announce to support 4 stereo streams instead of one 8ch stream. RPi4 has HDMI2.0 outputs, maybe its VC4 firmware can support the 4x2 configuration via 4 alsa devices. Perhaps RPi developers at Raspberry Pi Forums - Index page would know more, HDMI is a proprietary technology with no official documentation online. Also the seller should know more (theoretically ).

Hi, i had a "8channel 4x2" hat and i send it to suptronics to reprogramm it into the real multichannel Version 7.1 and i got this version back. But this Hat is discontinued. Suptronics told me there will be a new board for the rpi4, but nothing happend :-(
