Just come back to this having lost any configuration which may or may
not have worked last time and am not getting far.
I've tried the stdout approach:
Code:
--------------------
squeezelite -a 16 -o - | flac - -f --best --endian=little --sign=signed
--channels=2 --bps=16 --sample-rate=44100 -s -o
"/var/lib/squeezeboxserver/recordings/`date +%Y%m%d_%H%M%S`.flac"
--------------------
Starts, but playback of anything doesn't like it (jumps and stops)
and
Code:
--------------------
squeezelite -a 16 -o - | arecord -f CD | flac - -f --best -s -o
"/var/lib/squeezeboxserver/recordings/`date +%Y%m%d_%H%M%S`.flac"
--------------------
which appears to play and leaves a silent file behind
as does this loopback approach:
Code:
--------------------
modprobe snd-aloop
--------------------
create /etc/asound.conf:
Code:
--------------------
pcm.mycard {
type hw
card 1
}
ctl.mycard {
type hw
card 1
}
pcm.myconvert {
type plug
slave {
pcm "myrecord"
format S16_LE
}
}
pcm.myrecord {
type file
format "raw"
slave.pcm "mycard"
file "| arecord -f CD | flac - -f --best -s -o
/var/lib/squeezeboxserver/recordings/`date +%%Y%%m%%d_%%H%%M%%S`.flac"
}
pcm.!default{
type asym
playback.pcm "myconvert"
capture.pcm "mycard"
}
--------------------
giving:
Code:
--------------------
aplay -L
X11 connection rejected because of wrong authentication.
xcb_connection_has_error() returned true
X11 connection rejected because of wrong authentication.
xcb_connection_has_error() returned true
null

--------------------
and starting squeezelite with:
Code:
--------------------
squeezelite -o myrecord
--------------------
I'm guessing that I'm missing something quite stupid as the source plays
into my squeezelite recorder and a file is dumped. Just that it doesn't
contain any audio.
