Hi everybody,
i am just playing a bit with piCorePlayer to prepare a multiroom
environment.
Right now i am using a LogiLink USB Sound Box 7.1 (LOGILINK UA0099).
The matching asound.conf i found somewhere here in the forum or
somewhere else on the internet, can't really remember...
Whoever created it, thanks for the hard work!
I did some minimal changes to get the input streamer work and handle the
order of sounddevices getting mixed with alsa
sometimes (in the original config the card was identified by id not the
name: card 1 for example). This was leading to
onboard sound devices changing the ids of the cards from time to time
after reboots (Big thanks to Paul for the hint).
Code:
--------------------
/etc/asound.conf:
#########################################################################
## Channel splitting your UA0099 USB sound card to get up to four
## independent stereo outputs (...and more )
#########################################################################
## stereofront = the FRONT labeled green jack
## stereosurround = the SURROUND labeled black jack
## stereocenter = the CENTER / BASS labeled yellow jack
## stereoback = the BACK labeled black jack
## stereoall = all stereo outputs
##
## for up to eight mono output channels use:
##
## monofrontl = the FRONT labeled green jack - tip
## monofrontr = the FRONT labeled green jack - ring
## monosurroundl = the SUROUND labeled black jack - tip
## monosurroundr = the SUROUND labeled black jack - ring
## monocenterl = the CENTER / BASS labeled yellow jack - tip
## monocenterr = the CENTER / BASS labeled yellow jack - ring
## monobackl = the BACK labeled black jack - tip
## monobackr = the BACK labeled black jack - ring
##
## you can also use the line input as streamer input:
##
## pcpinput = the LINE-IN labeled blue jack
#########################################################################
#########################################################################
## labels and colors could be different for differnt vendors or
## versions of the device (Logilink, Sewell, Sweex, ...)

--------------------
I changed the sound settings:
Code:
--------------------
sudo alsamixer
with F6 choose the ICUSBAUDIO7D card and configure the levels
change PCM Capture Source to Line (to get the input streamer working)
sudo alsactl store
--------------------
Restore the sound settings after reboot and start the squeezelite
instances.
Code:
--------------------
/opt/bootlocal.sh:
sudo alsactl restore
sudo /usr/local/bin/squeezelite -n "XX (front)" -o stereofront -a 80:::0: -m
b8:27:eb:c1:09:21 -C 5 -z
sudo /usr/local/bin/squeezelite -n "XX (surround)" -o stereosurround -a
80:::0: -m b8:27:eb:c1:11:23 -C 5 -z
sudo /usr/local/bin/squeezelite -n "XX (center)" -o stereocenter -a 80:::0:
-m b8:27:eb:c1:13:25 -C 5 -z
sudo /usr/local/bin/squeezelite -n "XX (back)" -o stereoback -a 80:::0: -m
b8:27:eb:c1:15:27 -C 5 -z
sudo /usr/local/bin/squeezelite -n "XX (all)" -o stereoall -a 80:::0: -m
b8:27:eb:c1:17:29 -C 5 -z
--------------------
Prevent Squeezelite Autostart and activate Streamer Audio Input:
Code:
--------------------
Tweaks -> Audio Tweaks -> Streamer for Audio Input - set to Yes
Tweaks -> Audio Tweaks -> Squeezelite - Automatically start Squeezelite when
pCP starts - set to No
--------------------
Manually set the streamer input (not possible via gui right now).
Code:
--------------------
/usr/local/etc/pcp/pcp.cfg:
STREAMER="yes"
STREAMER_IN_DEVICE="pcpinput"
--------------------
To stream the input of the card add on the LMS some favorites:
Code:
--------------------
http://ipofpicoreplayer:9100/S32_LE/44100/2/M (MP3 Format)
http://ipaofpicoreplayer:9100/S32_LE/44100/2/F (FLAC Format)
--------------------
Beware: sound qualitiy of the input is bad for me (maybe better use a
hifiberry
or something similiar for that purpose, though the quality of the other
outputs of
card is good).
Every change that required a reboot was saved.
Code:
--------------------
sudo filetool.sh -b
--------------------
This is what is working so far...
I want to expand the setup with a second similar card (don't have it
right now).
But then i am running again in the ordering problem, since i cannot
identify the
card by name any longer in that case.
I read a bit on the internet about alsa and you can set the order and
also handle
the multiple cards problem with settings in /etc/modprobe.d/alsa.conf
(or alsa-base-conf).
So i tried that by setting the device order manually:
Code:
--------------------
/etc/modprobe.d/alsa.conf:
options snd slots=snd_usb_audio,snd_bcm2835,snd_bcm2835
#options snd_usb_audio index=0
#options snd_bcm2835 index=1,2
--------------------
Added the file to the filetool and saved:
Code:
--------------------
/opt/.filetool.lst:
etc/modprobe.d/alsa-base.conf
--------------------
But neither the old index method nor the newer slots method worked.
Does the loading of the modules happen before the filetool backup
is written back?
With this method you can normally also address the problem with
multiple cards of the same type for example (vid and pid you get via
lsusb):
Code:
--------------------
options snd-usb-audio index=1,2 vid=0x0ccd,0x0d8c pid=0x0028,0x000c
--------------------
I know this is a more complex setup but here are finally some
questions/feature requests:
1. Would it be possible to add choosing an in asound.conf as self
defined Streamer for Audio Input - Input Device via the web gui
instead of setting it manually in pcp.cfg?
2. The Basic URL and examples Under Tweaks - Streamer for Audio Input
seem to be outdated:
http://picoreplayer:9100/S16_LE/44100/2/F has to be
http://picoreplayer:9100/S32_LE/44100/2/F
3. When you do not deactivate Tweaks -> Audio Tweaks -> Squeezelite -
Automatically start Squeezelite when pCP starts
there were some busybox errors when starting the piCorePlayer with
multiple squeezelite instances and the Main Page
is not correctly showing that squeezelite is running. This is
probably because the startup script is watching the process
and cannot handle multiple instances. Could the startup script be
modified to handle this?
4. This one is connected to number 3, would it be possible to change the
gui to add multiple squeezelite instances instead
of doing this manually in bootlocal.sh?
5. Is there a way for the user to add the posibility of handling the
alsa problems with /etc/modprobe.d/alsa.conf?
Cheers Reiner
