this can not be normal, something seems to went wrong, ake a look to the journal:
When PulseAudio needs to pass audio from one module to another using incompatible sample-rate (for example, playback at 96kHz to a card that only supports a maximum of 48kHz), specifies which resampler to use. You can use the command
to list all available resamplers and choose the best tradeoff between CPU usage and audio quality for your taste.
Tip: One of the major complaint about PulseAudio is its high CPU usage in some use cases. A lot of these cases happens when pulse needs to resample multiple streams (individually). If you intend to mix multiple sample rates often, consider creating an additional sink at the correct sample rate which you can then feed back to your main sink, resampling only once.
…but from me here only half of help, solution will be needed toooo…
