Hi Juanito

If your hardware supports hmdi audio, ...

Or is that HDMI audio?

Many abbreviations are backwards here - MRI = IRM, AIDS = SIDA - with the end result that I’ve little idea what I’m saying 🙂

Hi Juanito,

So I used the Googled AI as  to find out what the Winsystems ppm-c407 supports, I could read the doc's but I just wanted a quick answer.

Yes, the WINSYSTEMS PPM-C407 supports HDMI audio.
Based on the available information:
MiniDisplayPort: The PPM-C407 features a MiniDisplayPort interface.
Audio Support: This interface, as listed in the specs, supports audio along with video.
HDMI Compatibility: MiniDisplayPort and HDMI are related technologies, and MiniDisplayPort can carry digital audio signals that are compatible with HDMI.
Explicit Mention of HDMI Audio: One source specifically mentions the SYS-398Q-2G-0 (which might be related or have similar features) and its support for HDMI 1.4 Type A Stereo audio. This suggests the PPM-C407 is likely to also support HDMI audio through its MiniDisplayPort interface.
Therefore, while the datasheet mainly mentions MiniDisplayPort, the PPM-C407 does support audio output through its MiniDisplayPort interface, which can be connected to an HDMI display for both video and audio.

And then I stopped being lazy and this is from the manufactures datasheet

The PPM-C407 is a full-featured embedded single board computer that operates in the
Windows 7, Windows 8, Windows 10, Windows CE, Linux and DOS environments. It
features an Intel® Atom™ E3800 Processor, up to 4 GB soldered DDR3 RAM, PC/104
and PC/104-Plus bus connectors (stack-through connectors are optional), as well as
optional fanless operation. It provides 24 lines of 5 V DC tolerant digital input-output
(DIO), and also video output with audio support. Communication interfaces include
Gigabit Ethernet, four USB 2.0 ports, two serial RS-232/422/485 channels and two
serial RS-232. channels. Refer to “Features” on page 2 and “General Operation” on
page 4 for specific information.

Video Interfaces (Intel Gen7 Graphics, one or two simultaneously active displays)
• Mini DisplayPort (version 1.1)
• Video Graphics Array (VGA up to 2560 x 1536)
• Low-Voltage Differential Signaling (LVDS, 18 or 24 bpp)

This above is just informational, and your Tinycore has worked on this card since version 10.
And thank you for all you do.

Hi Rich

I mentioned that after loading the graphics-KERNEL.tcz that my display and font size shrunk.
It was too small for my poor eyes.  So the following boot parameter fixed that.  Now I'm happy with the display and Alsa

Code: [Select]
