Hello,
i am find difficult to make my soundcard can make sound, i read the handbook but not working so well (i am attached image screenshot the soundcard default). i am using Laptop Lenovo Legion i5 8300H gtx 1050 mobile
Make pcm0 default, pcm1 is a recording-only device so it isn't going to output any sound: sysctl hw.snd.default_unit=0
If the system automatically chose pcm1 for you, let it know it's wrong by putting hw.snd.default_unit=0 in /etc/sysctl.conf
Then use mixer to check and adjust output levels.
Be aware there are currently problems about PulseAudio getting pulled as a dependency of many packages such as your Plasma desktop and enabled without asking (see this topic if you're interested in the details).
I can't tell from the icon if your sound applet is audio/plasma5-plasma-pa or audio/kmix. Make sure to use plasma-pa if you use PulseAudio and KMix if you don't. As an alternative to KMix you can also try audio/dsbmixer.
If you still have no sound, try disabling PulseAudio in Plasma's autostart settings.

In my case it was Realtek ALC662. I cured the problem by run sysctl dev.hdac.1.polling=1.
If it helped put that code to /etc/sysctl.conf for apply it every boot:
