I'm not hearing anything from the Chromium browser. aplay -l lists three devices:

card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: VT1708S Digital [VT1708S Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

In other audio-playing software, such as Audacity, I hear audio if I choose hw:0,0, but not with hw:0,1 or HDMI. (I have no HDMI devices at the moment.)

I suspect Chromium is sending audio to hw:0,1 or HDMI. How can I determine, from Chromium itself, which audio output it believes it's using?

Changing it to hw:0,0 is another matter for later.

  • if you are using pulseaudio, the gui pavucontrol will show in the output tab an animated VU meter of the device getting the audio.

You can use pavucontrol to change the audio device of chromium:

sudo apt install pavucontrol
pavucontrol
