Re: PecanPi -- Next Generation Raspberry Pi DAC and Streamer

Hello, I am evaluating a FPGA reclocker + slave DAC configuration for my RaspPi. Does PecanPi make both RaspPi and PCM1794 slave to an external master clock ? Is this configuration comparable/superior to RaspPi Master + reclocker ? Does the RaspPi kernel injects some jitter by its own (independentl...

Re: PecanPi -- Next Generation Raspberry Pi DAC and Streamer

I have had multiple questions regarding volume control on the unit.

The volume control can be either through the knob on the unit or through software when you control the device remotely.

The HW volume control on the unit (knob) will be better than to the SW one. Both will sound great.

Re: PecanPi -- Next Generation Raspberry Pi DAC and Streamer

Thanks Orchard Audio, I added "Orchard Audio ApplePi DAC" and "Orchard Audio PecanPi DAC" to the piCorePlayer "Audio output device" dropdown list/configuration. It should be available in the next version of piCorePlayer. Obviously untested, but I can't see there is much of a chance of a problem occ...

hi OrchardAudio,

Does the PecanPi use the ApplePi overlay?

I haven't noticed a PecanPi overlay yet.

regards
Greg
It will use the RPI-DAC overlay, which is essentially identical to the one that you mention. Both will work.

Code: Select all

Re: Volume Control data over SPI BUS

If this is in addition to an (I2S) audio card then just create a codec driver that exposes a volume control mixer and add that as an auxiliary device in the card driver (aux_dev list in snd_soc_card or aux-devs DT property in the simple audio card driver). See for example the various amplifier driv...

No, it's all good. The overlay is extremely generic - all it requires is that the host has an I2S controller, labelled "i2s", an empty node called "sound", and access to the driver.
Thank you.

Re: ApplePi DAC, Highest Performance Raspberry Pi DAC Launches

Question: You state this is a dual mono DAC. Does that mean the left and right outputs will always be the exact same signal? I understand that is not what dual mono really means, but have to check. The left and right channels will be different. The DAC chip is used in monaural mode. This means that...

The overlay is added to the kernel now, and will be in all future firmware releases.
Does the overlay need to be updated to support the Model 3 B+?
