Hello, A few weeks ago a bought a sound card for my home studio. I was quite happy until I realized that all the soundcloud 's tracks lost their stereo. Here's the setups I tried: Soundcloud -> Firefox -> computer -> firewire cable -> sound card -> headset = mono Soundcloud -> Safari or Chrome -> computer -> firewire cable -> sound card -> headset = stereo Soundcloud -> Firefox -> computer -> jack 3.5mm cable -> headset = stereo Soundcloud -> Safari or Chrome -> computer -> jack 3.5mm cable -> headset = stereo Do you have any idea of what I might not doing well? In 2018, a guy seemed to have the same issue: [https://translate.google.com/translate?sl=fr&tl=en&u=https://fr.audiofanzine.com/techniques-du-son/forums/t.661973,soundcloud-en-mono.html https://translate.google.com/translate?sl=fr&tl=en&u=https://fr.audiofanzine.com/techniques-du-son/forums/t.661973,soundcloud-en-mono.html] Thank you !
