    Huh? Sorry I don't understand.

    E2A

    tc@PCP-XLR-LMS:~$ e2fsck -ny /dev/mmcblk0p2
    e2fsck: Only one of the options -p/-a, -n or -y may be specified.

    In any case fsck cant fix the free count issues as the fs is mounted.

    It's pretty clear to me, you cannot combine options.

    Yup, no argument on that front! But there's no point passing just 'y' to fsck since the vol is mounted i.e.


    tc@PCP-XLR-LMS:~$ e2fsck -y /dev/mmcblk0p2
    e2fsck 1.45.6 (20-Mar-2020)
    /dev/mmcblk0p2 is mounted.
    e2fsck: Cannot continue, aborting.

    I'm confused as to what you're suggesting.

    My question in case it wasn't clear was about why fsck in read-only mode indicated free count issues if fsck had been run on boot? Or does fsck not fix those?

    There is something I wanted to ask since I ce back to using pCP few months ago.
    Will rt-kernel ever come back? I always felt it sounded better (not only with pCP but also with Daphile).
    Another option would be to offer a way to load custom kernels (a script?).

    Thanks a lot.

    You cannot run fsck to make repairs on a mounted file system. When fsck runs at boot, the file system is not mounted, so it can run normally. If your filesystem won’t get repaired, it is likely a failing sdcard.

    The biggest problem is a functioning kernel. Nobody in a semi official channel maintains a working RT kernel for rpi. If there is a working kernel, then itĺs just packaging the kernel modules.

    Ok I found the issue.

    I pulled the sd-card, and remember that I could just use another RPi to check it via a USB adapter. I also loaded the 'e2fsprogs.tcz' extension to enable badblocks. Both checked out Ok.

    Code:
    tc@Touch-pCP:~$ e2fsck -n /dev/sdb2
    e2fsck 1.45.6 (20-Mar-2020)
    PCP_ROOT has been mounted 2 times without being checked, check forced.
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    PCP_ROOT: 5745/3899392 files (0.3% non-contiguous), 781874/7773184 blocks
    
    tc@Touch-pCP:~$ badblocks -v /dev/sdb2
    Checking blocks 0 to 31092735
    Checking for bad blocks (read-only test): done                                  
    Pass completed, 0 bad blocks found. (0/0/0 errors)

    After replacing the sd-card in the LMS RPi it again showed free count errors.
    Then I realised that LMS was active and so after stopping LMS fsck was fine.

    Code:
    tc@PCP-XLR-LMS:~$ e2fsck -n /dev/mmcblk0p2
    e2fsck 1.45.6 (20-Mar-2020)
    Warning!  /dev/mmcblk0p2 is mounted.

    pcp-bt8.tcz

    I did a clean install of 8 on a Pi3 with HiFiBerry DAC. Iwas previously running an older version with no problem.
    I'm now getting the following when I try to install Bluetooth;

    I/O Schedulers

    Just a detail but I understood that starting with kernel 5.x, linux supports multiqueue schedulers: mq-deadline, multiqueue bfq, kyber etc. If this is the case, the bit about elevator options seems outdated under advanced settings. Reading some comparisons, I chose none. I continue to have sensational speed both with a rpi4 and a pi zero.

    Analog output

    I successfully did in situ updates on a few piCore players, but one player fails to play after updating.

    This is a Pi A+ that I use with analog output in an old transistor radio to make a portable player. The player connects to the wifi network, Squeezeplayer is running, and "Headphones" is the selected output device. I tried different output settings, but that made no difference.

    If I hit play, there is no audio output and the playback indicator doesn't move from zero, i.e. playback doesn't commence.

    I also tried a clean install of pCP8, and that shows the same behavior. If I reinstall pCP7, everything works.

    All my other players use a HAT of one type or another, and these all work, which leads me to suspect that using analog output might be my problem.
