When I select the FM receiver, I find a radio station, the sound is heard on REC OUT(L,R), REC TAPE1(L,R),REC TAPE2(L,R) on high-ohm headphones, the sound regulation does not work.
The output reacts when I connect the record player to PRE OUT FRONT L, the sound is heard in the speaker but the sound regulation does not work. Then it does not matter what I chose on the front selector.
I replaced the capacitor C303/0.047F, nothing changes.
I'm asking for help, what should I do next?
Thanks in advance!... -

Hi, i've got problem with Dell Vostro 5490.

5. Both speakers are good
6. After installing the drivers from the Dell website, the devices visible in the manager:

Got a bunch of Motorola Minitor V pagers from Fire Departments here trying to fix some out of the non working ones. These pagers are known for either no sound / audio or they don’t charge. The internet is full of suggestions like metal shavings inside the speaker?
Anyway so I took one of the Minitor’s apart for my amusement in order to see why that is and nobody can fix em.
There are no service manuals or schematics for these that I know of. However… I did find the problem!
On the main board of this unit where the speaker connects to there is a metal shield.... -
Hello.
I have an issue with HP 8470p - rather strange one.
I have a noise and sound distortions on both internal speakers and external speakers, when I plug such into the 3.5mm audio jack.
Seems like the noise is present especially when I play audio, where there are parts/sections where the volume of the actual recorded sound is low.
Interestingly, when I play the windows sound test, everything seems to be almost okay. The sound/distortions are similar to when you have interference from some other piece of equipment nearby or when you have an audio receiver with bad amplifier...12-31-2021, 10:25 AM
