Design and build beaglebone based audio streamer board and reconfigure Linux ALSA -

Purpose of Board:

Receive audio signal via Ethernet using ARM board and output ALSA audio to discrete TDA1545a DAC

What I have:

Beaglebone Black with OEM RTOS image connected to Cape with Reclocker and i2s audio signal output

Auth chip

Schematics/Diagram for Cape


I need someone to design and build prototype:

-Streaming audiophile quality Ethernet ARM board connected to a discrete TDA1545a DAC for streaming use (all IC’s on 1 board , no Sitara kits allowed)

-TDA1545 has perfect midrange, bass is weak. How can we improve bass?

-RTOS image modified to run on this board

-ALSA needs to be reconfigured to output right-formatted i2s instead of left-formatted i2s

-Tie i2s block to a TCXO 44.1 clock

-Audiophile Switching Independent , Isolated Power Supply, Low Ripple like iFi

-Add additional 12v 2A power for external Amp
