[free-electronic-lab] PulseAudio bug && FFT

[Developer Web developer]

I have a problem with PulseAudio.

$>lsmod | grep hda

$ dmesg | grep hda

hda-intel: Invalid position buffer, using LPIB read method instead.
hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger

No mic available in alsamixer.

Would be glad for any help. John
