    I have not used the amp in months. I never did the firm ware update. Pluged in yesterday and no sound/volume from amp. Did the suggested firmware upgrade and still no sound??

    1. Strange. Have you ckeck with another cable ? If you have active pickups, have you check the battery ?
      I assume you tried to adjust volume and master knobs already? Does music streaming still work ?

    Maybe spark 40 was great until I tried to update it. There was no sound and four blinking LEDs after attempting a firmware update in 2021. I emailed with support and tried their various suggestions [tried a different USB port on the computer, a different computer altogether, delete and reinstall updater, and perform a factory reset on the amp (which I was unable to do because the blinking LEDs just kept blinking)]. I sent in the log (which contained info generated when I tried to update), but that didn’t lead to a solution, either. I registered the amp when I got it, but unfortunately I bought it second-hand, so it was not covered by a warranty. The best they could offer is for me to send it to an authorized repair place for $99, which I didn’t do. Has anyone else had this problem? I see there are several spark 40s for sale on eBay that look brand new, but are listed as ‘for parts, not working.’
    Any advice?
