I have the same issue. Sound card works with 127 kernel and with 4.15.xx under Kubuntu 18.04 but fails to work under 128 kernel. Moreover, it causes Plasma load about several minutes until error line in dmesg appear hda_intel azx_get_response timeout switching to single cmd mode this is my sound card 00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) At the end, after next reboot under 128 sound card disappears from lspci completely and do not appear even if I boot to any other kernel or even other OS. I have to disable it and enable back in BIOS in order to appear back in lspci.
