Problem with audio clipping
One some models, certain audio mixer settings may result in very "harsh" and distorted sound both on the internal speakers and on headphones plug. This is especially evident when the played audio has high volume (i.e., full dynamic range).
This is caused by a hardware flaw: excessive internal amplification saturates the audio channels, resulting in clipping.
Solution: reduce the volume on the responsible mixer channel(s). e.g. in the console alsamixer with control via arrows: up/down left/right.
