In my experience, this is a lie.
It is enabled in the ALSA device named "default". That doesn't help
with programs that hardcode a device name like "hw:0".
You could try something like the following to find any programs that
still try to use "hw":
pcm.my_hw {
@args [ CARD DEV ]
@args.CARD {
type string
default 1
}
@args.DEV {
type integer
default 0
}
type hw
card $CARD
device $DEV
subdevice -1
}
pcm.dmixer {
slave.pcm "my_hw:1"
...
}
pcm.!hw = blow_up
(You could also redefine "hw" to another valid device, but it would be
a better idea to adjust the configuration of the respective program to
use the correct device.)
This version has been rock-solid for a couple of months now:
pcm.!default {
type plug
slave.pcm "asymed"
}
# This is the audio output:
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:1,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}
ctl.dmixer {
type hw
card 0
}
# This is the microphone
pcm.dsnooped {
ipc_key 1027
type dsnoop
slave.pcm "hw:1,0"
}
# This makes both channels work together.
pcm.asymed {
type asym
playback.pcm "dmixer"
capture.pcm "dsnooped"
}
I am very happy now! Thanks for all your help!
An update after continuing to be happy for nearly two years - thank you
people! I am hoping this latest question will involve only another
straightforward tweak - the only thing that has changed is that I am now
up to Fedora 25 x86_64:
I now want to use "recordmydesktop" which is working fine with the mic
but not recording sound from videos that are playing eg from YouTube or
local mpv etc - hopefully an alsa guru will have a solution for me?
Thanks,
Phil.
