Oops, the hdmi device does not take a second parameter.
Use:
playback.pcm "plug:hdmi:0"

Ah.  I based it on what I had worked out years ago for my main workstation

CL>   pcm.!default {

unfortunately that gives:

This disables all automatic sample rate/format conversions.

Replace it with:

  pcm.!default {
type asym
playback.pcm "plug:hdmi:0,0"
capture.pcm "plughw:1"
  }

[Alsa-user] configuring asoundrc

2021-02-02 Thread James Cloos 
i'm tryin to get audio to work on a new board.

so far nothing i've tried works.

aplay -l reports:

 List of PLAYBACK Hardware Devices 
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 0: ALC888-VD Analog [ALC888-VD 
Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 1: ALC888-VD Digital [ALC888-VD 
Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

my goal is to default to the first one in that list.

[time passes; looks like i found a partial solution...]

this:

pcm.!default {
type hw
card Generic
device 3
}

ctl.!default {
type hw
card Generic
}

reports:

aplay: set_params:1349: Channels count non available

but some gui apps succeed, so that does not seem fatal.

nonetheless, any ideas on how to fix that?
