Volumio VS Raspian: mounting external USB drives

Ok, Im a tad, ok a LOT confused here.

As you know if youve read any of my posts, Im having almost zero luck getting sound from 2 different HW and SW setups regardless of how I try it.

Here’s what I got:

(2) RASPI 3B+
(1) Audio Injector Stereo DAC
(1) HIFIberry DAC+
7" HDMI screen
generic usb mouse and kbd
WIRED network connection
(1) seagate backup plus external USB drive 4TB drive that has all my music

last night for grins and because I wanted to get SOMETHING that worked sound I went w/ the Audio INjector DAC and plugged a headset into the 3.5 port ON the DAC

Loaded Raspbian whatever the latest img is 8/6?

loaded the audio injector drivers AND the test scripts and got test tones through my headset, nothing through my rca yet

then I tried to access my USB drive, not seen, tried to mount every way to Sunday to no avail

I tried MANY different cli commands to load the info on the drive and some of them didnt make a ton of sense (warning very large device attached sda) was only one id never seen before, loaded NTFS support and everything elkse I could think of NADA,

I was loading gpartd to repartition the drive into (2) 2TB when i realized it was 0030 and I had to get up in 4 hours

then today at work i remembered

Volumio identified, browsed and read from my drive just fine as (1) 4TB drive, somewhere along the way volumio proved i didnt need to break the drive up

BTW: Just to kill time, I downl;oaded an MP3 from a teachiong site I use and played IT through the headphones just fine.

i am SOOOO confused.

I would REALLY love to setup volumio, I loaded raspbian trying to demonstrate a known good configuration, and I ALMOST got there…

any ideas?

I would really really love to help… Except your soundcard is not supported by volumio…

MIchaelangelo:

which one? please dont say both,

Ive seen folks post that the HIFIBERRY worked

the audioinjector well Im gettinbg to the point as to why THAT isnt supported

Yes, the hifiberry is supported, the Audioinjector is not.
For the hifiberry, please try to remove all other peripherals or to hook them to a powered USB hub, I suspect you’re having a power issue
