I’m frustrated

M-Audio AV 30 speaker problem: Left speaker doesn't play as loud as right speaker.

My AV 30 speakers that are connected to my computer are having a problem all of a sudden: the left speaker plays much more faintly than the right speaker.

Verified it's not my computer:
- Verified the speaker balance in Windows is set properly to 50/50
- Plugging in headphones into the headphone plug in the speakers themselves plays properly in headphones
- Plugged headphones directly into the computer headphone jack and it plays properly

Verified the cables:
- double checked the stereo-to-RCA cable is working by plugging into another set of speaker
- tried another stereo-to-RCA cable and same problem occurs

Any other ideas or am I screwed?

    Many, many people have this problem. Out of warranty service is impractical if you have to ship since shipping and repair costs almost equal the price of the original. I replaced one set (I had two pair in the house) having this problem and now the other original pair has this problem too.

    There is a design flaw of some sort and not normal, random part problem.

    M-Audio really ought to solved this design flaw long ago given the number of people having this problem over the years.

    If it weren't for this, I'd heartily recommend them to people but you would have to plan on replacing them every couple years.

  • I would agree, that the repair should be posted online or available as a kit. I have the same problem, getting a different brand this time.

  • Fixed mine finally. Replaced the two 220uf caps and the 15v 1w zeners with 5 watt.
    Also replaced the 4558 and the TL074 and repaired the power connector. None of this actually fixed the left side issue. I read more about this problem and it appears that the 22uf caps near the edge of the pcb between power connection and phono jacks are the issue. I replaced them with 10uf that I had on hand and it's working.
    No need to trash them if you can solder.
