Connecting external cd player

[haines]

I have a Mini Multmedia Player to play cd disks . It has an HDMI port. I run it through a Ycbueno USB-c capture card to the USB-C port on my computer. This is a 4K@60Hz to USB3.0 Full HD 1080P/60fps, HDMI Capture Card . However audsacity cannot see the drive.

haines,

Welcome to Gentoo.

The drive is not actually connected to your system, so will not be seen.
Your Ycbueno USB-c capture card is what is connected. The system may see that. It has no knowledge of the capture card input.
It may also need kernel drivers.

To help wit kernel drivers, we need the output of

, so we can seed the Vendor and Device ID of the capture card.

I post the entire list because there are several I cannot identify. But none look like my Mini Multimedia Player model DVP-508

It seems the kernel fails to see the drive at all: I have no /dev/sr0 interface. I'm getting a drive known to be linux friendly, needs no driver and has a USB rather than HDMI output port.

As Neddy already said. The PC can only have the knowledge of the drive if it is either directly connected or your capture card does a path through of the device.

Does the capture card provide this functionality or does is work on a different setup/pc?

haines,

Your device is a capture card, not a CD drive. The kernel will never see a CD drive.
USB connected optical drives will appear as a optical drive to the kernel.

You will likely have a USB Audio device, for the sound, and a separate, video device for the video.
Used together they can capture HDMI video, with the sound track.

looks like it may be a capture card.
Indeed, putting 534d:2109 USB into a search engine, leads me to an Amazon review which says

This is another device based on the

MacroSilicon MS 2109 chip, like many other capture devices.

This means that full resolution output is only possible in compressed MJPEG format or at very low frame rates (5 fps). Lower resolutions are supported, and it will run at 50 fps (some resolutions) and 25 fps (all resolutions) as well as 30 and 60 fps. This is good for PAL countries!

So you get a compressed video stream, its a USB2 device after all.
Its a UVC (Universal Video Class) device, so you need that support in your kernel.
That will give you a /dev/videoX where X is a number, that will be used to get the video stream.

This page discusses the audio capture.

In short, it can be made to work under Gentoo as a capture device. The USB2/MPEG video means that the video resolution will be poor, or you trade frame rate for resolution.
It cannot control the drive as its a media grabber only. It has no controls and no knowledge of the input source.

Thanks I'm replacing the HDMI drive with a drive known to be Linux-friendly and has USB port. I assume my lack of /dev/sr0 is because the kernel sees no drive, and without that interface my hopes to play audio are dashed.

haines,

You can play audio through the USB Capture Card.
It cannot control the drive, you would have to do that.
