Nice advice, guys! I got it setup in app Mode. The overall objective
is to make this Pi Media Player as dumbed-down and generally kid (5 year
old) proof as possible.
Last step might be this: getting the apps to share audio streams. I
thought I had this working somehow using ALSA until I installed
Squeezelite. Squeezelite was working, but in trying to configure
correctly (which I don't know how to do) the DMix Plugin for ALSA I seem
to have hosed the sound output. I'm currently using the following in my
*/etc/asound.conf *file:
Code:
--------------------
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0666 # mixing for all users
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.dsp0 {
type plug
slave.pcm "dmixer"
}
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.default {
type plug
slave.pcm "dmixer"
}
ctl.mixer0 {
type hw
card 0
}
--------------------
This is my *squeezelite_settings.sh *file contents:
Code:
--------------------
# ===========================v1.10==============================
# CHANGE THESE VALUES IF NEEDED
# The name for the squeezelite player, do not use spaces (default the hostname
# will be used):
#SL_NAME="Framboos"
# Note: "Framboos" is Dutch for Raspberry... :-)
# ----- SOUNDCARD -----
# Set the soundcard
SL_SOUNDCARD="dmix:CARD=audioinjectorpi"
#
# For Logilink USB soundcard UA0053, use:
#SL_SOUNDCARD=""default:CARD=Set"
#
# For Behringer UCA 202 USB soundcard, use:
#SL_SOUNDCARD="front:CARD=CODEC,DEV=0"
#
# For alsaequal, use:
#SL_SOUNDCARD="equal"
# ----- MAC ADDRESS -----
# Uncomment the next line (remove hash) if you want to change the mac address
(-m option):
#SL_MAC_ADDRESS="00:00:00:00:00:01"
# Note: when left commented squeezelite will use the mac address of
your ethernet card or
# wifi adapter, which is what you want.
# If you change it to something different, it will give problems
if you use mysqueezebox.com .
# ----- SERVER IP ADDRESS -----
# Uncomment the next line (remove hash) if you want to point squeezelite
# at the IP address of your squeezebox server (-s option). And change the IP
address of course..
SB_SERVER_IP="192.168.10.65"
# Note: if this is not set, Squeezelite will use auto discovery to
find
# the LMS server, which works fine too.
#
# For the standalone LMS server tutorial, use:
#SB_SERVER_IP="127.0.0.1"
# ----- AUTO PLAY -----
# Uncomment the next line if you want squeezelite to start playing on
startup. BE AWARE: If you use this, you
# should also uncomment and fill-in SB_SERVER_IP (see above). Otherwise this
will not work.
#SL_AUTO_PLAY="Yes"
# Uncomment next if you want to auto play a certain favorite, only (a unique)
part of the favorite's name is sufficient.
#SL_AUTO_PLAY_FAV="3FM"
# Uncomment next if you want to auto play with a certain volume, use a value
from 0 to 100.
#SL_AUTO_PLAY_VOLUME="45"
# ----- MISC SETTINGS -----
# Uncomment the next line (remove hash) if you want to set ALSA parameters
(-a option, set to buffer size 80).
# format: <b>:<p>:<f>:<m>, b = buffer time in ms or size in bytes, p =
period count or size in bytes, f sample format (16|24|24_3|32), m = use mmap
(0|1)
#SL_ALSA_PARAMS="80:::0"
# Uncomment the next TWO lines to turn on logging (-f and -d option):
#SL_LOGFILE="/var/log/squeezelite.log"
#SL_LOGLEVEL="all=debug"
# Uncomment the next line if you want to start the squeezelite daemon with a
specific user.
#SL_USER="pi"
# Uncomment the next line if you want to start the squeezelite daemon with a
specific working directory
#SL_WORKING_DIR="/home/pi"
# Uncomment and change the next line if you want to use a different
squeezelite version.
#SL_DOWNLOAD_URL="url to squeezelite zip file"
#
# NOTE: Dowload url should be for a zip file named
"squeezelite-armv6hf.tar.gz", the zip file must contain a squeezelite
executable named "squeezelite".
#
# If you want to use different squeezelite options, not set by this script,
use the next line:
#SL_ADDITIONAL_OPTIONS=""
# =========================================================
--------------------
Only thing I need to do is have all outputs of all apps regardless of
user share the audioinjector sound output - thus, from what I understand
DMix should do it.
Should I go ahead and install either Jack or PulseAudio?
Thanks guys!
