I am developing the PCB of CM6646. Do I need to flash the firmware or install the driver for CM6646? After I plug it in, the device list only shows WIN USB DEVICE;

Hello! I'm having difficulty processing some products using CM6646, can you share the development documentation or a copy of default firmware of this chip? Thank you!

Hello, I'm looking for the output impedance of CM6631A in ohms.

Hello, I wonder how I can download this chip SDK for MCU & DSP programming?

I plan to use the CM108AH to inject sound from microphones on the Android platform, but I'm experiencing significant delays in signal reproduction. Additionally, some of Cmedia's more advanced components aren't malfunctioning. What better solutions does Cmedia recommend? Please help me! tomb of the mask

I have a sound card with CM6206, the one you can get on Ali Express for $10. The issue is with the driver. Sound keeps cutting off until I either reconnect the USB cable or switch between audio devices in Windows audio settings. I was using this device without a driver for a while. It didn't cut off then. Though the sound quality was definitely worse (tinny and with no lows ). Now I switched to SPDIF which doesn't work without the driver. I tried connecting to a different PC with the same driver. Keeps cutting off. This happens multiple times during usage with irregular intervals. Very annoying. OS is the most recent Windows 11.

It is needed to connect capacitors to ground to DREG33 and DREG18 pins ? If yes which capacitors are needed?

I intend to use the CM108AH to inject sound from microphones on the Android platform, but I am encountering a large delay in signal reproduction, other more sophisticated components from Cmedia do not even work, what better solution does Cmedia propose?

We purchased a C-Media CM6631A PRO device. We will use this product to receive ASIO 192khz MPX signal in the processor software of our radio station. In the sound setting of the computer, 24bit 192khz is selected, but we cannot go above 48khz in the ASIO4ALL program. Can you send Win7 and Win10 Drivers?

Where can I find driver for my USB Sound Box CM6206-LX?

Hey everyone, I recently purchased the Razer Seiren V2 X microphone and decided to take a quick look at the internals. It seems to have a Cmedia CM7030 chipset for which I could not find any specifications / datasheet. I believe this might be a very new chipset. Is there a way to get the datasheet for this chipset? Many thanks, R
