Hi all, I posted this on the Tiny Core forums, but thought I'd include it here too as it's based around piCorePlayer.
I just managed to get ShairPort installed on my piCorePlayer installation. By configuring ALSA to use the dmix (direct mixing) plugin, I now have both apps working without stepping on each others toes. To test the 'worst case' scenario, I've been playing music through both apps at the same time, and it's producing the mixed output from both sources. It's been playing for a few hours now, so it's looking really promising. I will test it more over the next few days, trying different scenarios. In any case, I've included the steps below in case anyone else finds this useful. I really hope it works flawlessly, as I'd love to have my SqueezeBox-based players also support direct streaming from Airport devices. In my setup, I'm using a Behringer UCA202 USB DAC, but I believe these steps will work with any USB DAC, as long as it's the default ALSA device. Cheers, Pete PREPARATION Burn the piCorePlayer image to the SD card: https://sites.google.com/site/picoreplayer/ Expand the second partition: (refer to the 'System with pre-installed extensions' section) http://distro.ibiblio.org/tinycorelinux/5.x/armv6/releases/README Install nano: Code: -------------------- tce-load -wi nano -------------------- SHAIRPORT Install shairport: Code: -------------------- tce-load -wi shairport -------------------- Create the shairport script: Code: -------------------- sudo nano /usr/local/etc/init.d/shairport -------------------- Add the following to the shairport script: Code: -------------------- #! /bin/sh # /usr/local/etc/init.d/shairport # NAME="piCorePlayer" case "$1" in start) /usr/local/bin/shairport -d -a "$NAME" -b 95 ;; stop) killall shairport ;; *) echo "Usage: /usr/local/etc/init.d/shairport {start|stop}" exit 1 ;; esac exit 0 -------------------- Set the execute permissions for the shairport script: Code: -------------------- sudo chmod a+x /usr/local/etc/init.d/shairport -------------------- Configure the boot script to run the shairport script on startup: Code: -------------------- sudo nano /opt/bootlocal.sh -------------------- Add this line to the bottom of the boot script: Code: -------------------- /usr/local/etc/init.d/shairport start -------------------- Add the shairport script to the backup file list (to ensure it gets persisted between reboots): Code: -------------------- sudo nano /opt/.filetool.lst -------------------- Add this line to the bottom of the backup file list: Code: -------------------- usr/local/etc/init.d/shairport -------------------- ALSA MIXER Configure the mixer to ensure multiple apps can share the sound device: Code: -------------------- sudo nano /etc/asound.conf -------------------- Remove or comment out the original lines in the file, and add the following: Code: -------------------- pcm.!default { type plug slave.pcm "dmixer" } pcm.dsp0 { type plug slave.pcm "dmixer" } pcm.dmixer { type dmix ipc_key 1024 # the key must be unique ipc_key_add_uid 0 ipc_perm 0666# permissions - octal notation slave { pcm "hw:0,0" period_time 0 period_size 1024 buffer_size 8192 rate 48000 #or 44100 } } ctl.dmixer { type hw card 0 } -------------------- Set the volume to maximum: Code: -------------------- sudo alsamixer -------------------- Code: -------------------- sudo alsactl store -------------------- SQUEEZELITE Set Squeezelite to use the default ALSA audio device (to ensure the ALSA mixer get used): Code: -------------------- sudo nano /usr/local/sbin/config.cfg -------------------- Comment out the first line below, and add the second line: Code: -------------------- #OUTPUT="sysdefault:CARD=ALSA" OUTPUT="default" -------------------- -(Note: the above change can also be done via the piCorePlayer web page, under Squeezelite Settings > Output settings)- SAVE CHANGES Ensure the changes are persisted between reboots: Code: -------------------- sudo filetool.sh -b -------------------- Reboot the device: Code: -------------------- sudo reboot -------------------- ------------------------------------------------------------------------ petar's Profile: http://forums.slimdevices.com/member.php?userid=50217 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
