tas5721EVM usb connection's problem with VirtualBox

Hi, Hongkun,

I don't understand your situation.

You got it working fine on a Windows machine, but when you try to run it on your Mac it doesn't work?

A couple of us use Macs, but we boot windows. I take it you don't have a dual boot Mac?

no, i mean, i just have a mac, but the controlconsole must be installed on a windows,

so, i have to install a windows(win_xp) on my mac by virtualbox.

My question was about the usb connection's problem, but it is solved.

I am facing another trouble. The USB-miniEVM is recognized by windows, but i can not adjust the device volume.

Could you please give me some recommendations?

Thanks and regards,

Hongkun

Hi, Hongkun,

I don't have an EVM with me right now, but can you adjust the volume on the TAS5721 GUI?

Hi Don,

No, I heard no sound.

As mentioned, the windows find it, I also can set the EVM as USB audio device.

But I can't adjust the volume. The Screenshot can show us that it doesn't work. 

I don't know why!

Hi, Don,

I use PBTL mode and can adjust the volume on GUI, but can not adjust on windows.

On the Status Bar I also can not find the drop down box, it is maybe a problem too.

Could you please give me any ideas?

Regards,

Hongkun
