Hi,

Because of a bug-report about power-saving related plops/clocks on a
Lenovo T470s, I've asked inside Red Hat if people with a T470s and
running a recent kernel were also experiencing this.

Most people are happy with the audio, but I did get a few bug reports
about plops on the headphones-jack.

Is this a know issue? and/or is there anything we can do about this?

p.s.

One important thing which I forgot to mention, when using headphones
the plops are mostly deemed as acceptable. They become a real problem
when using the headphone jack to connect to an external amplifier,
then the plops are amplified by the external amplifier and they
become a real problem.

Regards,

Hans
