    You need a scope.
    Because its audio problem. You need to see the output and where it stops.
    Try with the dmm and see if you got mV on the chip.
    Just cook it! It's already broken.

          i think that it not detect speaker/HF. What signals must have to detect speaker/HF?

            Check the HP jack. Stupid, i know, but that could be the culprit.

              Philips F9217L-50R speakers – build quality impressions and DIY surround repair
              by momaka
              More Lo-Fi speakers and another DIY surround repair. The patient this time: a pair of Philips F9217L-50R speakers from a budget Philips rack/component system from the '80's. The system belongs to my brother in-law… or actually his parents. However, they didn't want it when they moved houses and he liked it anyways, so he ended up keeping it. It's a pretty cool-looking vintage system with a wood/veneer cabinet and shelves for records and cassettes. Unfortunately, I didn't get a chance to take a picture of it or get the model #'s (but maybe next time I visit, if anyone is curious?)

              ASUS ROG G513QY – RX 6800M powered but not detected intermittently + random crashes (Motherboard: 6050A3254002-MB-Axx)
              by EvazX
              Hello everyone,

              I am working on an ASUS ROG G513QY laptop with RX 6800M dGPU.
              Originally, this laptop was completely non-functional. I replaced the motherboard (part number 6050A3254002-MB-Axx), and with the replacement board it started working fine.

              For a long time, the dGPU worked perfectly stable. I played several hundred hours on very demanding games such as Cyberpunk 2077 without any crashes, instability, or detection issues. Performance was excellent and there were no warning signs of failure.

              However, after some time, the replacement motherboard...

              Logitech R20 speakers - Replacing one of the speakers.
              by Widget
              Hi guys,

              I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.

              Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.

              Printed on the back of the Logitech speaker is;

              OLD eMachines T6520 BIOS Request!
              by grimacelord
              Hello,

              I know that this is probably a long shot, but I figured if anyone could find this BIOS, it would be you guys.

              I am working on an (old) eMachines T6520 desktop PC that might have a corrupt BIOS.

              Model:
              eMachines T6520

              Motherboard markings:
              MS-7145B0505068731
              RS480M
              7145 v2.1 RS480-A21+SB400-A23

              Symptoms:
              The computer does power on, CPU fan spins, but does not POST. No display.

              Troubleshooting steps so far:
              Replaced the CMOS battery (which was in need of replacing)
