Really hope someone can point me in the right direction.
I have a RPi 2 with an IQaudiO DAC+ running Volumio 1.55, all connected through high quality interconnects to a good amp and decent speakers. I have tried playing mp3 and flac of varying quality and the sound is just not nice! I get better audio quality playing the same tracks through a 3.5mm jack from my phone.
At first i thought it was the power supply. I have since tried several including a battery to no avail. I have tried Volumio downloaded from here, and the version provided by IQaudiO. I’ve checked all of the various settings i can find on the forum. sudo aplay -l displays the board. /etc/modules has all of the right ones listed. alsamixer settings look correct.
I’m really not sure what is going on. To describe the sound, its like it loses all clarity, high notes especially vocals become distorted and buzzy. Everything starts to merge with no depth to the sound. At first i thought it was just me, but I had a friend over the other day with no interest in hifi and he even asked if I was playing a particularly low quality file without being prompted.
I’m about to flash Volumio again in case i have been unlucky with two bad flashes. But any help would be appreciated, I’m getting to the point of sending the board back.
