I am getting stuck in the configuration for PulseAudio. I compiled and installed PulseAudio normally without any issue, but the system had no sound. Tried to delete rm ~/.config/pulse/*, set pacmd set-default-sink , modify the config file /etc/pulse/default.pa and a lot of solutions on many forum. But none of them helps. I am using Glibc 2.28 and Gcc8.2, followed steps as in BLFS 8.3 books.

Here is some error when starting pulseaudio

Any help, please?
