Other Parts Discussed in Thread: TAS6421-Q1
Hi,
I bought the eval kit TAS6421Q1EVM to test I2S audio amplifier.
I do the same as documentation (www.ti.com/.../slou415.pdf part 3.5.1) :
- Power supply of 14.4V
- Usb connected to PC
- All switch UP
- Connect à 4ohm load
The PC detect the card as sound card, but when I play sound, there is nothing on the board.
So I install the application PurePath Console and try to use the dedicated app, but the app show that the board is offline (as you can see ont the picture).
On the board (as you can see on the picture), the LED WARN is on.
I don't know why the board doesn't work. Do I need to do something else ? Or the board is broken ?
I need to check quikly if the audio amplifier is OK for us to integrated him in new pcb design.
Best regards,
