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?

Help, please! Can anyone tell me where to find the driver for the CM8738? Thanks in advance! smash karts

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.

CMI8888 card behaves normally under Windows but behaves erratically under Linux. Can only be written to during cold boot, but may be noisy. After rebooting, writing is no longer possible. Do you have any additional drivers, patches or other information that might be helpful?

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

Hello. What is the output impedance of your product in ohms? My product: CM6631A

Hi, Can I request for the design files of CM6646 evaluation board. Thanks.

Hello, which of the following chips is the best for headphones with vibration?  I'm interested in the Xear function, the effects of different environments combined with vibration. In the past, I had SOMIC G909  headphones with one of the versions of CM108, and I liked them. Perhaps someone knows which of these chips is actually more advanced?

Hi all, I work on a pcb board with CM119B and 93C46 EEPROM. I have some questions: How to read and write on GPIO, have you a sample code for LINUX? It's possible to read and write on EEPROM directly on linux? Write and Read a name board and serial number. Have you a driver or code sample on linux to help me ? Thks

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?

What does it mean when, while streaming an audio file, the LEDO is flashing at approx. 2 Hz rate but at times, it slows to half that rate and streaming audio stops for a few seconds, then resumes, as does the LEDO rate

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?
