    Bisogna tener presente che se hqplayer e/o hqplayerd partono all avvio di sistema prendono possesso ,in esclusiva, dell uscita audio, gli altri Player no, compreso roon...quindi potrebbe essere quello...

    Some relevant points:

    1. The DAC is Ayre QX-5 Twenty
    2. Connection protocol is USB
    3. There was not loose connection - I double checked. Also...
    4. ... it works perfectly when running Roon player on the same system
    5. Finally, regarding the syntax " 2>&1 | tee " is just a shell technique to:
      • redirect both stderr and stdout to the same stream (2>&1)
      • duplicate terminal stream to named file (tee )

    Further from the user...

    I had a couple of exchanges with Piero today. Even with the non-R2 version of squeezelite, I was getting the same failure case. On the console, I was seeing a very peculiar error:

    USB 1-1.2.3: clock source 40 is not valid, cannot use

    Piero suggested I play around with squeezelite settings to limit the rates, etc. Then I had a sudden brain wave. Since my Zenith SE's built in player is also squeezelite (except it boots into a different Linux), I mounted the boot ssd and poked around. I finally discovered they use the following options with squeezelite:

    -n -s localhost -m ,mac address. -o hw:CARD=Interface -a 16:4:: -D

    I duplicated these settings and voila! It now works. I think the key is the -a and the -D setting.

    Wow, that was not obvious!! But I am happy.

      • duplicate terminal stream to named file (tee <file>)
    The problem IS alsa lost and gain repeatedly the connection to the card, that is what ALSA says in the log. We could then investigate why it happens.

    If with ROON is playing seamlessly, then probably the fault is ROON stealing the CARD to other players (what is using ROON to connect to the card other than ALSA?), I keep my doubts about why it happens only after 2 minutes, but...

    If it so, the solution is to Kill ROON and others before to start squeezelite.

    BUT:

    What about HQP or other players in the same system?
    It happens also with other dacs?
    It happens also in other (audiolinux) systems?

    if answers are "the same" and "yes", it should be handled in OS; i.e. orchestrating init.d scripts (or whatever is used to start services) to ensure that only one player is active at one time.

    If only squeezelite is having this trouble, in every system, we should make sure the version in use is compiled using the same version of alsalib in use in the target system, but I believe this is already ensured at distribution (audiolinux) level.

    Squeezelite logics don't need to be modified, il launched with -C 1 will release the connection after 1 sec of silence and it will NEVER steal connection if not available, but sure it will spot an error when the connection is lost, whatever is the reason and aborts if launched when the required device is not available.

    I could not think of any better behaviour.

Since my Zenith SE's built in player is also squeezelite (except it boots into a different Linux), I mounted the boot ssd and poked around. I finally discovered they use the following options with squeezelite:

    -n <player-name> -s localhost -m ,mac address. -o hw:CARD=Interface -a 16:4:: -D

    Wow, that was not obvious!! But I am happy.
    mmmh....


    I do believe the difference is mostly here:
    -o hw:CARD=Interface. That means direct access to the device. I'll try that before any other.

    that said,

    -D = use DOP for DSD, it was playing flac, is not taking place here.
    -a 16:4:: are alsa buffer,period size, format and mmap. 16 is a very little buffer, default is 40:4::, that with that card in audiolinux results in 40:4:S32_LE:1

    We should look at your log to see what alsa parameters (format and mmap) it uses, but they are depending on the OS and the card.

    There is a (little) chance that the last one (mmap) could be
    involved in the problem, but only if audiolinux (or alsa in audiolinux) is compiled without the mmap support, in that case you should add -a 40:4::0 to the command line (to use same defaults values) and NO mmap, if you are not sure, 0 is safe, so try to use it first.


    Then you could play with other settings.

    this is the line I currently use, when not using DSD.

    -n squeezelite-R2-o hw:CARD=J20 -x -m 00:e0:4c:68:ce:78 -r 44100-768000 -c aif,wav,pcm -b 1048576:1048576 -a 499:3::0 -f /var/log/squeezelite-R2/squeezelite-R2.log

    -b is the input/output buffer, should be equals when using uncompressed pcm, the out should be 1/0.75 the imput when using flac for best results, but it does not really matter with so little alsa buffers (< 200). In this case is 2GB, that way the song is almost always in RAM, the network inactive and CPU get 400/16 fewer interrupts from memory, but be sure to have enough RAM or decrease them.

    Ciao, Marco.

    Quick question - will removing the C-3PO plugin disable upsampling/conversion of the original files ? I have few DSD256 content but my DAC supports only DSD128. How do I down-sample in this case ?

    In C-3PO just disable DSD256 as supported rate.

    Thanks for helping me to understand squeezelite better. I will post followup questions here directly, if you don't mind my doing so in English!

    I now have squeezelite/LMS working perfectly, and I also have it working with Roon. This is my preferred configuration, since I want the Roon experience, with the sound quality of squeezelite, which is significantly better with the -b option. I am currently using:
    OPTIONS="-n zenith-se-player -s localhost -m ac:1f:6b:26:ed:32 -o hw:CARD=Interface -b 1572864:1572864 -a 16:4:: -D"

    However, with Roon as the server, I am getting random skipping of tracks, sometimes in the middle of the current track. Is this a known problem? It seems to be Roon's LMS emulator to blame, as LMS doesn't have any issue. I tried playing with the first -a setting, going all the way up to 499. 499 changed the sound signature a bit, but it didn't solve the problem.

    Open to suggestions.

    You are welcome!

    Too bad I'm not an expert in ROON, so I can't really help you in this matter. Some time ago we had problems with PCM/WAV files longer than x minutes, where x where depending on bitrate, almost 20 at 384KHz/32bit, but C-3PO and Squeezelite-R2 solved the problem. It seldom happens, listening to Qobuz, that the track skips to next, but I believe is due to Qobuz, not LMS, I've never investigated. What I would do is trying to verify if it always skips at a precise position in the length of the track, if so I'd open a ticket with ROON.
