Hello
Thank you for the SW.
Simulation working well.
But if I connect TLV320DSC3100EVM-U demo board.
Program have error while reading initialization script.
Reistallation, reboot not solwe this problem. I create screen shoot.

Please help

Attached screen shot.

Perhaps you need to update the firmware. You should follow the steps in the following wiki link and see if it works now: e2e.ti.com/.../2790.how-to-revive-a-usb-audio-evm

Hello Ivan
Still not succes.
I successfully download USB-AudioEVM0304_441KHZ.BIN into EEPROM.

But CodecControl software still can not find connected USB-miniEVM.

FYI: I´m using OS:Windows 7 Professional 64bit.

Josef,

Have you followed the last steps (16 and 17) of the instructions? Is the device still being recognized by the PC as USB-miniEVM instead of USB-AudioEVM?

Hello Ivan

I repeated whole procedure again. And I also changed the sampling rate to 16 kHz. According the  TLV320DAC3100-Q1 datasheet. Without success.

Please help.

Josef,

This is really odd. I've been using this GUI with no problem on my EVM boards.
Is the device recognized by the GUI when you use the general version of CodecControl as a different device (say TLV320DAC3101 or something like that)?

Hello Ivan

I must change in the Europe  Windows decimal comma into decimal dot.

CodecCotrol for TL320DAC3101EVM start and show connected not recognized board.

After that happen also Codec Control Software for TLV320DAC3100EVM-U start working. May be missing driver file in TLV320DAC3100EVM-U distribution.

Headphone drivers working well. But I cannot hear anything from 8 Ohm loudspeaker.

Please help, how can I switch on Loudspeaker?

Josef,

Glad to know it's finally being recognized.
I think you need to add 0R resistors on R18 and R19 in order to let the speaker output work fine. This board is designed for both stereo and mono devices. For mono devices you must add these resistors on the speaker outputs.

Hello Ivan

0 Ohms resistor are already fitted.
If I want play sound through the loudspeaker. I must set up D2 bit in register  Page 1 / Register 42 (0x2A): Class-D Speaker (SPK) Driver

Its look likes on Error in DAC3100.txt init script
