I just bought new medium-grade Sennheiser 4.50 headphones, but I'm hearing some distortion in the bass through my computer. My BF connected it to his tape player and there was no distortion. He then tried his headphones on both, and there was no distortion from his tape player, but there was from my computer.
So I'm concluding the problem is not in my new headphones, but in my sound card. (My BF noted that my headphones had an impedance of "only" 18 ohms, and he said that was significant.)
Actually, dialog from Netflix sounds okay, but my music collection does not. Perhaps by upgrading my headphones I'm hearing artifacts I couldn't hear before.
My question: do I need a new sound card? Do sound cards wear out? My computer (a no-name generic) is at least 5 years old, and when I bought my computer, the sound card came with it.
I don't even know how to determine what make of sound card I have. (Please tell me -- I prefer a command-line method.)
I'd also like recommendations for a new sound card, if that's what I need. And of course, it has to be compatible with Linux (that's why I'm posting this here).
EDIT: Elsewhere I posted that I accidentally turned the sound up too high and probably damaged my headphones. (That was before I bought the Sennheisers.) Could the high volume have blown out my sound card instead? I mean, I'm getting sound, just not good sound.
