Eu tenho um novo laptop HP-15-BS576TX que possui este Áudio HD Point-LP da Intel Corporation.
00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d71] (rev 21)
EDIT: Eu enviei um relatório de bug para o Bug Tracking do Ubuntu: link
O som do laptop funciona perfeitamente no Windows 10 com drivers da realtek. No entanto, no Linux, o volume é bastante baixo, e eu preciso rolar o controle deslizante de volume acima de 100% até o máximo para obter algum som. Eu suspeito que o som não está vindo de todos os alto-falantes (talvez existam subwoofers para este modelo). Detalhes sobre o hardware de áudio estão abaixo:

Eu passei pelas fontes de kernel Linux ALSA e Snd-HDA e não encontrei nenhuma otimização para este laptop. link link
Tente isto:
Edite o arquivo abaixo:
/etc/pulse/default.pa
E certifique-se de que a linha load-module module udev-detect tenha esta aparência:
load-module module-udev-detect ignore_dB=1
e reinicie o servidor PulseAudio:
pulseaudio -k
Em seguida, teste novamente.
