Well, with this patch, while I can get it to seemingly initialize
without errors by replugging, I can't actually get it to work. Jack
says:
Starting jack server...
JACK server starting in realtime mode with priority 10
self-connect-mode is "Don't restrict self connect requests"
Acquired audio card Audio1
creating alsa driver ... hw:CARD=hiFace2,DEV=0|-|1024|3|96000|0|0|nomon|swmeter|-|32bit
ERROR: ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to capture-only mode
Released audio card Audio1
ERROR: Cannot initialize driver
ERROR: JackServer::Open failed with -1
ERROR: Failed to open server
here's what aplay does when it tries:
aplay: main:830: audio open error: Invalid argument
strace of that says:
openat(AT_FDCWD, "/dev/snd/pcmC1D0p", O_RDWR|O_NONBLOCK|O_CLOEXEC) = -1 EINVAL (Invalid argument)
I dug up a different USB sound device (bithead) and plugged it in, it
still works just fine with the same commands.
The only difference I see in the alsa-info output is that
control.7 {
iface CARD
name 'Keep Interface'
value false
comment {
access 'read write'
type BOOLEAN
count 1
}
}
has gone missing. I've attached it incase you can spot something I
didn't (obviously the cards are in a different order which makes
things somewhat tedious for a direct comparison). Apart from the
device number on the usb bus, the lsusb -vvv output is the same as
it was in with 5.10.9.
