Right-click the Windows Start button and choose Device Manager.
You can do the dance above all day long or hit the solution below. Hey guess what, it’s time to reboot again! Now you really know where this is going (queue song: Round and Round…). Once the RealTek process initiates after reboot it detects the generic Driver that was re-installed by Windows and says, whoa hey dude we have to uninstall this existing driver in order to move forward. After rebooting, Windows identifies the missing driver and re-installs the generic driver from the local Driver Store before the RealTek install process launches and… you can probably see where this is going. The RealTek installer removes the existing generic drivers installed by Windows Update and requests a reboot so it can replace in use files. I used RealTek drivers supplied by Asus for my motherboard, and I tried drivers directly from RealTek. So I tried updating my audio drivers to provide the expected quality of sound and control. And that, is not why I have these Mackie CR3 speakers! No matter how many times I re-installed the Windows drivers, tried to adjust audio settings or enhancements the result was the same – terrible sound quality. If.I would be fine with the generic Windows driver for audio, if they worked! In my case the Windows Drivers generated terrible sound quality & the only option to correct or adjust was via the Audio Enhancements feature – which was broken and had no affect. One difference that will not matter for most users is the tools like hdajackretask for snd_hda_intel driver do not work for snd_usb_audio driver, but not many users want/need tools to hack internal codec configuration The online source code for package alsa-ucm-conf has a list of motherboards that should work without issues on latest kernels. The audio specfications are no different, but ALC4080 has additional amplifiers for audio outputsĪudio controls in alsamixer are very similar to ALC1200 codecs, but ALC4080 has an internal USB bus to connect to the additional amplifiers and pre-amplifiers, so ALSA playback and capture devices in aplay -l and arecord -l are shown as USB devicesĪLC4080 requires a Use Case Manager configuration to get the USB audio channels lined up correctly
