2 days before I started using arch linux. I've got some sound issues.

I've installed alsa alsa-utils etc., unmuted all channels with alsamixer. My user is in audio group.

I've also installed pulseaudio and started it with

pulseaudio --start
  • Command
    speaker-test -c 2
    
    does not make any sounds.
  • In pavucontroll (I'm using i3 but I don't think its matter) it's show up my sound card and this jumping line that something its playing sounds on it.
  • When I'm plugging headphones it's detecting it end switch sound device from speakers, but no sound either.
  • hwinfo --sound display this:

Yesterday I put off my laptop turned on for maybe an hour and sounds started working, but only to the next reboot. Anyone can help?

If it worked maybe it's cause you plugged in and audio device that shifted your default card number.

If you want a fast and easy solution you can edit (or make) your /etc/asound.conf like this: defaults.pcm.card n defaults.ctl.card n Where n is your primary sound device number.

Type on your terminal:
$ alsamixer
and press f6, it will show you every audio device plugged in. Use that number for your /etc/asound.conf

I've said this is a fast solution, if you boot your system with an external audio device plugged in it will probably shift the numbers. (while pluggin it after booting won't)
