Hi. I need default firmware for chip CM6571 output is PCM+SPDIF. can someone help me??? thank you !!!

Hi so I’ve been using this Plantronics Rig 500hd usb sound card for over 4 years and I absolutely love the sound quality from it, I want to add I have it connected to my Sennheiser 660s headphones and it’s amazing on how this tiny chip separates footsteps, gunfire and reloading in game not to mention pin point accuracy where enemies are. My problem is that this dongle/sound card does not get loud enough for my headphones and my question is, I’m curious to know what other audio companies use this dac chip in particular or any of c-media chipsets at that? If anyone has any leads I would be greatly appreciated.

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

Hi! Could you tell me where can I download the EEPROM configuration tool for CM6535?

We met 2 problems with CM108B After power ON/OFF for many times, the gateway can not recognize the USB device. USB DP has a 1.5k pull up in our design. USB DM is also high during power ON. When I add a 1.5k pull down to USB DM , USB DM goes to low during power ON. Then the device can be recognized. Why does this happen? When the device is recognized by the gateway. The information from USB device is not correct for the 1st time. Some data is missing. And the data is complete at the 2nd time. Gateway information : H38WL using Allwinner H3: Linux 3.4 ; H80WL using Allwinner H6 :Linux 3.10; Orangepi Lite H6 is the same, using Linux 4.9
