Metallic Audio on TM-5402 M3

[Bamboccio]

Hello,

I have had this metallic / distorted audio on my TM5402 M3 for ages and I never tried to fix it. I remember having read that it is a known problem.
Is it possible to do something about it?

Thanks!

Do you get the same noise on the analogue audio outputs?

 

[Bamboccio]

Yea I tried connecting a speaker to the left and right outputs and it is the same.

The only other option would be the S/PDIF to an external home cinema amp, or if it's possible, setting the HDMI to output bit-stream.

Wow - you made me check the options and I I actually found that I had this option set to Dolby spdif. Should I go for Dolby HDMI?

 

[ozumo]

Try them all! Dolby HDMI sounds like the option that would send the audio bitstream over HDMI for the TV or home cinema amp to decode, but relies on the connected display/amp being capable of decoding the bitstream. PCM means the receiver uncompresses the audio before sending it over HDMI. Dolby SPDIF will send the audio bitstream over the optical connector.

Thank you! Dolby HDMI sounds better! Many thanks!

PCM would be fine also

Thank you. Yes PCM is also good.
