![]() ![]() The McIntosh guy that handles this stuff basically told me that the DAC 2 never breaks down and it must be a driver problem. I was streaming from an iFi Zen Stream via USB. I may have to give up and use the laptop internal audio port to play music which is not as good as using the DAC on the MC7900. It seems to me that this is a class problem and perhaps no one else in the planet is crazy to use the Windows operating system to play music using the USB DAC on the MC7900. This intermittent Windows crash "DPC_WATCHDOG_VIOLATION" stop code 0x133 when using the MC7900 USB DAC is very difficult to resolve. Installed the old MCinstosh driver back and Windows is playing music over the USB to the MC7900 with the expectation that the intermittent problem is still present. In conclusion the new universal CEntrance driver versin 9.6 downloaded is not compatible with the MC7900 DAC. This is an indication that the new CEntrance USB DAC driver for the device is not loaded. However, the MC7900 was not showing on the display the bit/rate 32/192k. Run the new CEntrance driver installer utility. ![]() Second, used device manager to uninstall the old MCintosh CEntrance driver. ![]() The old CEntrance driver was still present. I implemented the plan of downloading and installing the CEntrance universal audio driver and it appears that the installer completes fine but the this driver is not connecting to the MCintosh DAC.įirst, installed the driver on top of the existing MCintosh driver to see if the device manager "Sound, Video and Game Controllers" shows the new driver associated with the MCintosh. After three days of working fine, Windows 11 just crashed as usual with "DPC_WATCHDOG_VIOLATION" stop code 0x133. ![]()
