    HP 8470p - distorted sound and noise when playing audio

    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 part. Some kind of static, distortions or interference.
    Tried different sound drivers and even live Linux - the problem is present nonetheless. But there is no static noise present, when I do not play anything.
    Could this be other issue with components around the sound chip or it is indeed defective?
    If I play any music or something, where the volume of the original recording isn't low, the issue is hard to notice, if present.
    It is rather puzzling issue. The sound card is IDT. HDAUDIO\FUNC_01&VEN_111D&DEV_7605&SUBSYS_103C17C6&REV_1001

    Useful conversions. I don't "speak" imperial. Please use metric, if you want to address me.
    1km=1000m=100000cm, 1inch=2.54cm, 1mile=1609.344meters, 1ft=30.48cm 1gal(US)=3.785liters, 1lb=453grams, 1oz=28.34grams

    Yamaha MOX8 boot freeze and distorted sound
    by maleksa
    My Yamaha MOX8 synthesizer recently developed two issues.

    Firstly, after booting up, it operates as normal. However, after about 5 minutes, the sound starts to get distorted (broken up screeching sound) almost like putting it through a guitar distortion pedal. After a while, the distorted sounds will go away for a while and comes back. At times, the synthesizer will also freeze I need to power off and on again.

    Secondly, when powering off and on again, there will be times where the synthesizer will freeze during the boot sequence (freezes at the MOX8 Opening Screen),...

    what i went through dealing with my mobo with dead onboard sound!
    by ChaosLegionnaire
    so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

    i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

    Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
    by LEECH666
    Good day ladies and gentleman!

    I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

    This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

    I think the PSU buzzing comes from one of the coils near the bridge rectifier but...

    Tele-master AS-20 amplifier. No output sound, just noise
    by Francesc V.
    Hi:

    I bought this amplifier from the 70s to try to repair it. So far it has no output sound, just noise. You can volume it up and down.

    I've checked fuses and all are ok.
    I've continued with capacitors:
    • The main black one should have 4700uF, but it has lost half of its capacity during these years.
    • The ones that I've numbered have still a really low ESR and the full capacity after ¿40 years?



    The 4 transitors are perfect. Desoldered and tested individually.
    There are also components which I don't know exactly what they are....

    Marian Trace Alpha sound card repair help
    by Christos Tsiligiannis
    Hello to the forum.

    My name is Christos, I am new to the forum here and i am posting from Greece.

    So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

    To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

    So i tried asking for a schematic from the company and they would not give me one. Instead they...
