Roon Core running on QNAP HS-251+ 1.5 (build 334) stable
PS Audio Directstream running RedCloud firmware
Output from Roon into DS can be either Ethernet Bridge/i2s/USB
When playing lower quality files AAC or MP3 sound quality degrades significantly with pops and crackles. If I play the same song in TIDAL/MQA /DSD/FLAC no issues at all. The problem occurs irrespective of the connection method (USB/i2s/ethernet)
I have isolated the problem to Roon by taking the same AAC/MP3 file playing it outside of Roon in jriver, BubbleUPNP and others all over different connection methods. When Roon is removed the same file plays with no issues.
I have tried every DSP setting, volume leveling and it makes no difference not even a slight difference.
