  1. I am starting this topic as I think some of us have hijacked another topic. @@Chanh and @@Tasso and @ appear to be busy with some very interesting things. I can see @ and @@statman and @@JDWest and many others being interested as well. I would like to use this post to discuss the BBB, Rasberry, Banana pro and Wandboard products as well as others. I would also like to understand how we use these products to play music from hard disks, NAS drives and the internet. I am not a Techie and can do some diy , but do not have time to read hundreds of pages on other forums which I must admit I do not understand I also acknowledge that this is an ever developing area, which actually makes it more exciting. So What do I need for the best budget playback at the moment and how do I do it?
  2. Since Logitech's discontinuance of the Squeezebox family of network music players the Squeezebox user community has made great strides in leveraging an alternative hardware platform to fulfill the role of a Squeezebox transport. In a nutshell this means that if you're looking to leverage Logitchemediaserver and the great controller apps that exist for Android and iOS (SqueezeCommander/ OrangeSqueeze and iPeng) as your digital playback backbone you're in luck. The community has built a ready-made Linux distribution called CSOS that can be installed on a Wandboard and turns it into a Squeezebox transport and/or server for Logitechmediaserver's purposes. You can then output the digital stream from the Wandboard to your DAC using its asynchronous USB input. Whilst CSOS is based on Fedora and does all that's required, I prefer to roll my own using Arch Linux - the principle reason being that Arch Linux is a pretty lean OS, meaning its less resource intensive and runs noticeably faster than CSOS. The downside is you need to put in the effort to "roll your own" so to speak. You can configure the Wandboard to simply act as a transport or alternatively you can configure the Wandboard as a standalone Logitechmediaserver and Squeezebox transport. To turn the Wandboard into a Squeezebox transport and/or player both CSOS and this RYO solution leverage an application called Squeezelite. I'm going to post the guide in parts to deal with different aspects of rolling your own transport/server so please bear with me because some of it is a work in progress. There's enough in the first post to turn a Wandboard into a fully functional Squeezebox transport. What you'll need: - Wandboard Dual or Quad - 8GB micro SD card -- get as quick a card as you can as its speed affects bootup time and load time of anything not in RAM. - Micro SD card reader/ writer to write the OS image to your micro SD card - if you want to configure your Wandboard from your regular PC / Laptop you'll need to connect the Wandboard to your home network - a SSH client to login to the Wandboard from your desktop/laptop. If using Linux, use ssh. If Windows, install and use putty - a DAC that has an asynchronous USB input Installation: The first thing you need to do is install Arch Linux to a micro SD card (8GB minimum). I highly recommend that you ensure the microSD is high-speed. To prepare the microSD and install Arch Linux CLICK HERE then click on the installation tab and follow the instructions. Before rebooting your Wandboard, connect it to your home network and your ADSL Router's DHCP (or whatever DHCP server you're using) will assign the Wandboard an IP on reboot. When you're done with that you have a working Arch Linux install on your Wandboard. All that remains now is updating OS components, customising a few things and finally installing and configuring Squeezelite and optionally Logitechmediaserver (should you want to use your Wandboard as a standlone player with HDD attached). Determine the Wandboard's IP using your DHCP server or use nmap if running *nix (replace 192.168.168 with the subnet you're using): nmap -sP The Wandboard is the device named 'alarm'. Login using SSH [username = root; password = root] (Windows users use putty): ssh root@wandboardIP Update OS, change hostname and install audio components: pacman -Syu hostnamectl set-hostname SqueezeWand pacman -Sy faad2 libmad mpg123 libao alsa-utils avahi wget Configure alsa - asound.conf file: nano /etc/asound.conf Paste in the following: pcm.!default { type plug slave.pcm "softvol" } pcm.dmixer { type dmix ipc_key 1024 slave { pcm "hw:0" period_time 0 period_size 4096 buffer_size 131072 rate 41100 } bindings { 0 0 1 1 } } pcm.dsnooper { type dsnoop ipc_key 1024 slave { pcm "hw:0" channels 2 period_time 0 period_size 4096 buffer_size 131072 rate 41100 } bindings { 0 0 1 1 } } pcm.softvol { type softvol slave { pcm "dmixer" } control { name "Master" card 0 } } ctl.!default { type hw card 0 } ctl.softvol { type hw card 0 } ctl.dmixer { type hw card 0 } Install Squeezelite: mkdir -p /usr/local/bin cd /usr/local/bin wget -O squeezelite http://squeezelite-downloads.googlecode.com/git/squeezelite-armv6hf chmod a+x squeezelite Configure Arch to fire up Squeezelite on startup: nano /etc/systemd/system/squeezelite.service Paste in the following: [Unit] Description=Squeezelite lightweight headless squeezebox emulator After=sound.target Requires=avahi-daemon.service After=network.target After=avahi-daemon.service [Service] ExecStart=/usr/local/bin/squeezelite -n SqueezeWand Restart=always [Install] WantedBy=multi-user.target Configure Arch to autostart squeezelite and avahi-daemon on boot: systemctl enable squeezelite avahi-daemon Connect the Wandboard to your DAC using a suitably insulated USB cable and ensure your DAC is powered up. Now reboot: reboot Following reboot your Logitechmediaserver should have a SqueezeWand entry in its players list (refresh your LMS browser window if necessary). All that remains now is to obtain your DAC string from Squeezelite, add it to the startup configuration and you're in business. Login using SSH [username = root; password = root] (Windows users use putty): ssh root@wandboardIP Have squeezelite list output devices: squeezelite -l You'll see a listing along the lines of the following (specifics will change based on the capabilities of your asynchronous USB DAC): Output devices: null - Discard all samples (playback) or generate zero samples (capture) sysdefault:CARD=sgtl5000audio - sgtl5000-audio, - Default Audio Device sysdefault:CARD=imxspdif - imx-spdif, - Default Audio Device sysdefault:CARD=imxhdmisoc - imx-hdmi-soc, - Default Audio Device sysdefault:CARD=Vivere384PCMDSD - Vivere384PCM-DSD, USB Audio - Default Audio Device front:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - Front speakers surround40:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - 4.0 Surround output to Front and Rear speakers surround41:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Vivere384PCMDSD,DEV=0 - Vivere384PCM-DSD, USB Audio - IEC958 (S/PDIF) Digital Audio Output Identify your DAC from the abovementioned output and edit the startup command line to have Squeezelite stream to your DAC: nano /etc/systemd/system/squeezelite.service Change the line ExecStart=/usr/local/bin/squeezelite -n SqueezeWand to incorporate reference to your DAC and set the real time priority of the output thread at high priority: ExecStart=/usr/local/bin/squeezelite -n SqueezeWand -o hw:CARD=Vivere384PCMDSD,DEV=0 -p 1 Reboot for the last time and in a minute or so you should be good to start playing files via Logitechmediaserver using the Wandboard. reboot In time I'll include guidance re adding Logitechmediaserver to the install and using the Wandboard as a standalone music server and transport.
