Volume of Squeezeplay 'jumping' when using SQPOS on Openpeak 7E


as on a recent thread in 'Marketplace', I have just bought one of the OpenPeak 7E units, with better internal speakers etc.

I've put Roobarb's SQPOS on it and is is mostly working. However the volume (of the internal speaker output) is jumping up an down, at intervals of roughly 10 to 15 seconds, from 'adequate' to 'way too quiet'.

My other running Joggler uses a USB DAC and the volume is fine both configured for this, and for using the internal speaker. Any pointers as to what might be up here?

Thanks a lot, Jon N

• I have Logitech Media Server installed on a home server (not sure of version, but < 7.8.0)). I do not use mysqueezebox.com (I don't have an account, even)
• I have two Jogglers on my home network. Both use wifi only and get IP addresses via DHCP. They are both on the same subnet as the server (Internet comms is not an issue).
• Both Jogglers run Roobarb's SQPOS, from a pendrive.
• I have (just now) realised that I should do individual Settings->Joggler Name from the SQPOS menu. I have given each joggler a different name, say "Joggler1" and "Joggler2". Until not I thought that having different IP addresses, and/or different hostnames, would disambiguate the two devices. I rebooted the Jogglers after this.
• in the Server Settings, there is a 'Player' tab. I assume this refers to the (single instance?) of the 'player' part of LMS, that sends audio data to (on or more?) clients. I have named this player 'vplayer' and reset the server
• No synchronising is set within LMS
• I can see the name of the individual Jogglers (Joggler1 or joggler2) coming up on the title bar of the SQPSOS screen

Player Model: SqueezePlay
Firmware: 7.7.2-r9710
Player IP Address: 192.168.0.44
Player MAC Address: 02:4c:e5:18:6d:60

Reading your last post jogged (pun intended!) my memory in that I had some funnies when trying to use MAC addresses in my router configuration to tie down IP address to given MAC addresses. The MAC address that LMS reports is the wired ethernet adapter MAC address whereas the router sees the wlan MAC address. So I think SQOS is messing about with the mac address that is used when connecting to LMS.

Not sure how this may help you as you seem to have 2 jogglers reporting to LSMS the same MAC address. Did you clone the USB stick once it had been setup on the first joggler? It is probably during first boot from a new SQOS usb stick that the mac addresses are sorted out, based on the hardware present at the time. By using the same usb stick image in another joggler, the mac address is carried across?

v3.03 (15th January 2015)
Kernel 3.18.2op4.
SqueezePlay for OpenFrame v1.60.
Added in a few more recent wireless card drivers as kernel modules.
Kernel panic reboot delay is now specified in the kernel config instead of in /boot/grub.cfg.
Kernel SCSI CDROM support (CONFIG_BLK_DEV_SR) now built-in to improve detection of WNDA3200.
We now handle MAC address generation completely. Pushed udev out of the loop.

• on the server, editing

  Code: Select all

  /var/lib/squeezeboxserver/prefs/server.prefs

  (after performing

  Code: Select all

  sudo systemctl stop squeezeboxserver

  ) and clearing out everything, or removing complete '_client:' sections, where the MAC address seemed to be spurious
• restarting the server with no jogglers powered up
• on each joggler, performing a 'reset all settings' [not just reverting Network to defaults]
• making sure to set the wireless network details, and setting the player name appropriately
• pressing 'Accept and continue' rather than anything else when commissioning the jogglers

I do recall reading somewhere that the wireless mac address is "derived" from wired mac address as the wireless card doesn't have one. Not sure how accurate this is as I thought all network devices would have their own unique mac address.

Anyway, have fun with them.

So you will see one IP from the OS and another IP on your SqueezeServer. It'll do the MAC thing no matter if you utilize the Gb NIC port or the WLAN USB stick port on the O2 Joggler and Openframe 1 device. It does the same with the Openframe 2 device except that has a combo blue tooth and WLAN mini PCIE card in it.

WLANMAC=`ifconfig -a | grep "wlan0" 2>&1 | awk -F\addr {'print $2'} | awk -F\  {'print $1'}`
ETHMAC=02"${WLANMAC: -15}"
