Sound Card Recommendations for the iMac


It looks like there is something wrong with the internal sound card in my iMac desktop. The music is now scratchy and mildly jumbled. Having eliminated every other possibility that I can think of - have others been required to replace the sound card and if so . . . .what did you get? Same stock part or upgrade?

I ended up reverting back to the previous version (from 7.0 back to 6.5). My wife later got an iPod that was incompatible with 6.5 so I upgraded again, (7.5), and had the same issues all over again. Went to Songbird, which was the only Windows player that could handle apple lossless files at the time.

I have crossed over to the good side now and have an iMac. There as some free alternative players for Macs out there, such as cog, vox,and songbird to name a few free ones. I recommend you download one of these and see (hear) if they sound better than your distorted iTunes.
Good luck,
thanks Arni I'll check into it!! Hope it doesn't destroy all the album artwork!
Hellofidelity and Arni: Just a follow-up note on the solution. I had upgraded to iTunes 9.0 and the trouble started. Today a buddy came over and suggested we see if iTunes had another upgrade. Impossible, I thought - its only been about a week. Sure enough 9.1.1 was available. We downloaded and problem solved. Music sounds great again. Thanks for you input, I appreciated it.
Thanks for the follow-up....hope all stays well and let the tunes keep flowing. ;)
Do either of you know how to go "backwards" and restore an older version of iTunes? As I stated above the improvement with the newest version is good but maybe I'm getting to picky since I still think I'm hearing some issues.
