Re: [SlimDevices: Plugins] HiFiBerry Amp Software Volume Control

just heard back from HifiBerry support who confirmed it operates in the
digital domain

So changing the volume will affect bit perfect playback

How is the dac done? Is it brown and burr?

I have the amp2 and works great!

Since someone asked about the amp function, what about the dac function?

Hi Markii

If the AMP HAT uses the same chip (TAS5756M) as the AMP+ then I'd be
fairly certain the gain control is digital.
The TAS has a wide range digital gain control but I see no mention of an
attenuator in the analogue domain in the datasheet.

Hope this helps

Jeff

[SlimDevices: Plugins] HiFiBerry Amp Software Volume Control

2022-11-17 Thread markiii


If I adjust the volume on such a Pi running a Hifiberry amp HAT using
the slider on Jivelite (or a USB volume wheel come to that)

does anyone know if this is adjusting the digitally in the DAC or in the
analog stage?

I can't find anything documented?
