That's cool! I messed around a bit with spinning mirror fan motors with PWM speed controls, but I never got it to work quite right.


Anyway.... Thanks for the detailed write-up on the C-Media driver installation.

Just out of curiosity, are you using the 8 channel DAC for laser control signals?

Umm ... that would be a no. :-) Someone gave me an old Yamaha 6-ch rcvr/amp and I'm trying to experience surround-sound for the first time (no lie). LOL

But I did build a spirograph-style "laser show" when living in the Everglades swamps for a few years. From a Dollar-Store laser pointer, 2 battery powered "personal fan" motors (also Dollar Store), 2 mirror chips from a discarded women's make-up compact (mounted at a slight incline on the ends of the motor-shafts, one shining into the other for 2 different projected circumferences and rotational frequencies), and a rheostat that balanced (or unbalanced) the voltage between the two motors (the rheostat was scavenged out of an old rusted junker-car's dashboard, its dimmer control). All mounted on another scavenged hunk of 1"x6" wood plank. Think "wilderness survivalist's minimalistic laser-light show". :-) The fun part is that it was so crude, just natural randomness in the dirty contacts and simple analog system made it continually and slowly evolve from simple to complex spirograph designs for hours and hours. It eventually got swiped by someone at an impromptu campground concert when I left it running all night on just 2 AA batteries for everyone's entertainment. :-)

That's as close as I've ever come to making my own "computer controlled" laser system. LOL

I just spent the good part of the last 10 days trying to get my ol' & reliable XP system to use one of these nifty USB sound cards. What with them going for as low as $10 now and flooding the markets, I bet I'm not the only one trying to get these to work with older OS's. Well, in my hunts, after I sorted things out, I found your page describing most of what everyone needs to know. But if you want the latest control panel with all 8 audio channels to fiddle with on an XP or Vista system, read on. Here's what I put in my "__READ_ME__.txt" file on my backup CD of all the driver incarnations I've tried.

--------------------

For Windows XP (and will probably also work with Vista & Win7).

To get the new full updated control-panel with the full systray utility:

First run the setup for the RHTS-2806 Headset with the latest drivers.

I obtained mine from the OEM's website.

(Unzip to your drivers work-folder of your choice.)

http://www.rosewill.com/wp-content/uploads/downloadable/drivers/driver_for_rhts-8206_windows_xp_vista_7_v1.0.zip

Reboot.

At this point you will only have control-panel options to select up to 6-channels.

The OLD version has full 7.1 channel support and playback/surround-sound options
for the CM6206-LX chip. (Even though you only have virtual control over the 2
extra channels.)


Now go to "add/remove" programs in the control panel, remove the
"USB Multi-Channel Audio Device".

Do NOT reboot.

Then install the very old "USB106-Full-04(0724)" program.

Mine was downloaded from here:
http://www.helpjet.net/dl/28706059-27657708-50712333/44107369/USB106-Full-04(0724).rar

(It also installs an ancient hellicopter-flying demo & a blasteroids kind of game.)

Do NOT reboot.

Go to your control-panel > system > hardware > device manager.

Expand the "Sound, video and game controllers" tree.

Right click on "USB Multi-Channel Audio Device", click on "Update Drivers"

NOW point it to the folder (if you unzipped it to a folder of the same name)

driver_for_rhts-8206_windows_xp_vista_7_v1.0\fscommand\XP\Driver\USB\

And let it update the driver.

You should now have the latest control panel with all the 8-channel
(7.1 surround-sound) features plus you have the latest driver.

While you won't get a full 8-channel output, there are options to swap
side and back channels on them (in case you want to play around with
choosing other audio channels from 7.1 recordings).

I still wasn't able to get more than 2-channel stereo on S/PDIF OUT, but
all the Analog OUT ports work just fine.

You also get to keep the twonky little surround-sound hellicopter demo
and "Rockwar" game (a little blasteroids type of thing) from the old version
to test your 3D sound effects.


The reason this works is that the OLD version installs the control-panel
and support files in XP's "\Windows\system\" folder, and the newer
versions install everything into where it rightfully belongs,
in "\Windows\system32\". When XP looks for files it checks the "system32"
folder first.


------------------


I had read that they found a way to enable all 8 channels for S/PDIF-OUT on MAC computers, has anyone
ran across something similar for Windows machines?

Now it compiles. I added an abs() to the int() function.

I try to compile LaserBoy_2017_08_06 on raspian stretch.
I followed the Raspberry_Pi.txt. Everything went well, except that this "error"

I am not sure if that is an issue ^^ Anyhow the code does not compile here

Looks like you're getting somewhere.

Does your scope have in intensity input?

You might be able to blank out the connecting lines.

There is a setting in LB to put O-Scope blanking in the 6th channel of a wave.

But that means you need a modified sound device that has at least 6 channels.

I'm trying to vectorise video. Still lots of tweaking to be done. An example is attached. (Not great quality for many reasons - it's 48-kHz output as I can't currently do both DC coupled output and 96 kHz.)

Can you share some pictures of what you are working on?

Thanks!
