Technical Questions / Allo DigiOne 192KHz/24 Music playback problem
« Last post by drsmiley on August 22, 2017, 06:58:41 AM »
I received my DigiOne on Monday (8/21/2017) and everything sounds great except 192kHz/24 music files.  The playback is slightly choppy and I can see on my amp (Teac AI-301DA} that the source indicator is slightly blinking during playback.  On all other sample rated music files (96kHz/24 and 44.1kHz/16), the source indicator is solid during playback.  The Teac AI-301DA user manual states that the indicators blink when the input is not a digital audio signal (Page 11). I also have an HIFIBerry Digi+ Pro that I used on the same raspberry PI3 and itís able to play 192kHz/24 music files with no problems.  Iím using Volumio 2.246 as the music source with the playback buffer is set to 12MB and buffer before playback is set to 40%.  The raspberry PI is connect via ethernet to my network. Is this a driver or board problem?

Thanks

Hi,

    You can use PIN no 8 and 10 these pins are not used by piano.You can find below technical manual for your reference.In that only highlighted pins are used by piano DAC.

Does Piano DAC use the RS232 TTL pins from RPI3 ? We want to use the RS232 (pin 8 and 10) on the RPI 3.
Is there a breakout for these pins on the Piano board ? If we don't want to plug in the Piano board what are the connections that needs to go from RPI3 to the PIANO ? just power and I2S ?

« Last post by stevenoey on August 09, 2017, 10:24:41 PM »
Hi,
I am not familiar with Ubuntu. Could you please list down the command line instructions to get the WIFI dongle to work?
Is there any setup guide on your website that I can download with regards to this matter?

Really appreciate your help.

Thanks.
Best regards,
