I’m using Ropieee as Roon endpoint, on my streamer (RPi3 + Hifiberry Pro as reclocker + Audio Gd I2s output module) connected to my Ps Audio Directstream dac via I2s. Roon is running on a Mac Mini i5 2014.
It works well, but there’s a file resolution limit at 24/192 and DSD64.
Using Dietpi on the same setup, limit is higher: 24/352 and DSD128.
Any hint to set the limit higher?
Thanks in advance.
Running Dietpi on the streamer, Roon shows 24/352 and DSD128 as maximum allowed.
Running Ropieee, it’s 24/192 and DSD64 instead.
I have another streamer, with Rpi3 and Allo Kali reclocker.
I cannot use Dietpi, because the Hifiberry Dac+ is required to run as Roon endpoint, but using Ropieee the frequencies limit is the same (24/192 and DSD64)
I’ve got a Hifiberry DAC+ Pro on an RPi running DietPi; it also reports being capable of 352.8kHz for some strange reason.
And I say ‘strange’ because, according to the specifications for the PCM5122 DAC (http://www.ti.com/product/pcm5122?qgpn=pcm5122), it supports “up to 384kHz”, but it does not have support for 352.8kHz (take a look at Table 8 on page 21 of the PDF).
I only noticed this behaviour when I tried playing a DSD64 album one day: Roon converted the album to a 352.8kHz PCM stream which resulted in the music being played back with slightly the wrong pitch. Setting the ‘Max Sample Rate’ to 192kHz fixed this, with the same album now converted to 176.4kHz PCM and played back with the correct pitch.
Bottom line: Something, possibly the Linux kernel, or the driver for this card (or both) is misrepresenting the card’s supported playback capabilities.
