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 <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

E: [pulseaudio] module-alsa-card.c: Failed to find a working profile.
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="2" name="2" card_name="alsa_card.2" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1""): initialization failed.

Any help, please?

Hi,
I have always just installed pulseaudio and left settings alone.
Maybe you need firmware and look at sound settings in the kernel.
