Any Developer With Openwrt & Also Audio Driver Experience?

Do Not apply If You Do Not Have Openwrt and Alsa Audio Driver Experience

Project overview

OpenWrt Development / New project

Expected to be completed by Dec 04, 2020

We have a project which is a Help Call system for the elderly. It's basically a fancy Voip phone running Openwrt and Asterisk on the MediaTek MT7688 CPU.

We are using a WM8960 codec connected via i2S to the CPU and we are performing some basic audio functions to check the audio (record & play) using arecord and aplay. We are getting some odd results such as noise being introduced and fast garbled recording. We suspect issues with the audio driver. It is possible some of the registers on the codec are being messed up.

We are looking for some direction as we need to solve the audio driver issues before we get the Voip calls moving through Asterisk.

Our first task is simply to play and record audio cleanly using arecord & aplay.

Any assistance/direction you can give is useful.
