    No sound when resuming after pausing

What happens is that after resuming play after a pause, no sound comes out even though squeezelite appears to be working. It then needs multiple re-boots until (for no apparent reason) it produces sound. It then carries on working. There is no low current or overheating going on when this occurs. It has occurred with 3.2x, 3.5 and today 4.0.

    I don't know if the cause is software or hardware and, to my untutored eye, the logs look normal except this pcp_boot.log. Any advice would be appreciated and if I should investigate any other logs, please let me know.

    Sorry if this is confusing to re-start a conversation from August but the problem has come back and I have been able to collect the pcp_squeezelite log to help diagnosis (hopefully)!

    To re-cap: periodically, after resuming after a pause or turning on after being off, the player looks as if it is playing normally but produces no sound. When it occurred in August, Paul asked for more detailed squeezelite logs. After a long period of working well, the problem has returned. The log is attached - I have cut out long periods of repetition to leave:-
    - Section 1 - from Boot to playing normally (sound OK)
    - Section 2 - paused
    - Section 3 - unpaused (looks as if it is playing OK but no sound)

    Grateful for any advice. It usually fixes itself after 3 re-boots but annoying comes back periodically.

    How are you handling muting control of the amp?

    In the mixer settings, the auto-unmute box is checked. Hardware jumper off.
    But none of that changes between the working and non-working states.

    The mute function on the board uses a gpio, make sure you are not using it anywhere else in your system (like lirc)

    hi kingswindsor,

    Your boot log looks like something is very wrong.

    You should only see "sh: 3: unknown operand" errors if there is a script error or corruption. Obviously, our startup code doesn't normally have these errors, so are you changing anything? or it might be the unique combination of your particular configuration.

    regards
    Greg

    Very strange. No, I haven’t changed anything other than that needed for normal configuration.
    The player is on at the moment (after various reboots to restore sound) and the boot log still shows the sh: 3: unknown operand errors. So it doesn’t seem to consistently stop it even if though its a bad thing.
    More curiously, because this has been going on for some time, I have rebuilt this player with a different RPi, different DAC & amp, different screen, different PcP versions, Lirc/no Lirc. The only things that haven’t changed are the power supply and speakers. I have probably used new SD cards too. I’ll do a fresh SD card install and swap out the power supply - but grateful for any other suggestions that might be more specific.

    Many thanks
    Does anyone have any suggestions please? I would have through a pi 3 with hdmi is a fairly common setup. How do you find the sound quality?

    Thanks

    Hi divbo,

    I just flashed a spare pi2 with pCP 4.0 and hooked it up-to my (now quite old) Yamaha 1800 receiver via HDMI
    I'm just listening to some Radio Paradise and a couple of albums in FLAC, and I have to say, I dont need a HAT DAC as the quality is excellent.
    no crackle or pop or any other misbehaving

    Maybe try a fresh write of pCP 4.0 and if that doesnt work maybe a differnt hdmi cable into a different input ?

    pCP devs, i used the wpa supp method to setup wifi too. great method. first time i've done a scratch setup of pCP for a little while now. this is really fast and easy.

    Is the volume set at 100%?
    You might want to try to go to the main page and install the ffpg library. I had a similar problem with a Marantz AVR and IIRC, that solved my problem.

    Hi guys,
    Thanks for your help with this. I updated to 4.0 but it seemed the same. Lowering the volume from 100 to 90 seems to improve things. Normally I use the volume on my amp and fix Squeeze to 100%. Is there a problem with the Pi's when set to 100? Why would this cause distortion?

    Cheers
