Arch linux sound problem

Question

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?

Answer 1

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)
