Public bug reported:
It seems as though an .asoundrc I created in my home directory is not
loaded, or the instructions are ignored.
I have been trying to get two stereo devices on one card into one four-channel
device (M-Audio FastTrack Pro), to use with jack and mixxx [0].
Currently I just have the following in it, provided by a very helpful Patrick
Shirkey (on the linux audio users mailing list) as a way to check that
.asoundrc was being handled [1]:
----8<----
pcm.mycard{
type hw
card 1
device 0
}
ctl.mycard{
type hw
card 1
}
----8<----
After putting that in the .asoundrc and running `sudo alsa-utils
restart`, I test it and get the following:
----8<----
~$ aplay -l

I would expect hw:mycard to be found, and the sound to play through card 1, but
it just fails.
