    AudioLinux and NUC Troubleshooting and Tuning

    Understood. My point was that Rufus, for example, does not recognize DMG as a valid format, so if your intent is to move the image between MacOS and the rest of the universe, an extra conversion to IMG might be needed. If you stay on MacOS, then DMG is fine.

    Sounds like there are enough options on how to save a USB disk to an image. Just for completeness, if you're on MacOS, you can also just use the built-in Disk Utility application. The quirk there is it saves the image as a DMG file, which can optionally be compressed and/or encrypted (which doesn't change the file suffix). If you're going to burn a replacement stick from the Mac, you're done. If you want an IMG file, you have to use a command line utility hdiutil.

    Does it do the reverse? Create an image from a USB stick?

    AudioLinux and NUC Troubleshooting and Tuning

    Actually, @romaz did not get the Toslink output to work on his NUCs, either with his early experiments with Adrian's Dream OS, or more recently with Audio Linux. See his post from the massive thread:
  5. Hey all, I've reorganized the 1st post and cleaned it up. Please take a look and encourage others to as well. Suggestions welcome.
  6. Yes, 8GB. You can't allocate 4GB of buffer space unless you have at least 8GB of RAM on the endpoint. As part of this, I trimmed down the AL footprint as much as I could. I posted these in my Tips and Tricks post on the AL troubleshooting thread.
  7. A word from the OP: We welcome your participation in this thread. Please note that discussion needs to stay focused on direct listening experiences with audio experiments discussed here. This is not an opinion thread. Most of what is discussed here does not have a readily available analytical explanation. Once we get into arguing about the why's, this thread is going to disintegrate. If anyone comes in here, makes no contribution, and attacks people, I reserve the right as OP to delete their posts. Further - this thread is about listening impressions. We do not: Demand proof Require a specific methodology Require measurements. For a synopsis of this thread, and an index of useful posts, please go to the first post in this thread:
  8. I'm creating a new post after this one, just so I can pin it to the top of the page. Regulars can please ignore safely!
  9. Please stay on topic. This thread is about direct listening experiences. We're not debating the "how does it work" here. For guidance, please look at the pinned post at the top of this page, and the first section of the first post of this thread. To your point, there are plenty of Rob Watts fans on this thread, and plenty of Blu2, HMS, Dave, and TT2 owners. The fact of the matter is that the upstream chain definitely matters. The mechanisms are not yet fully understood. While most of us would celebrate a DAC that was 100% immune to the quality (or lack thereof) of the upstream chain, we have yet to find one. Yes that includes the Chords. Please focus your participation here on reporting your listening experiences, or reading about others'. There are other threads to debate (endlessly) the mechanisms at work.
  10. I should have made this clear... I have no issues if I run LMS. The problems occur only when using Roon. So the bugginess is in the Roon implementation of LMS emulation, and Room have already declared they will not support software squeezebox players. That said, many of us do not want to give up the Roon user experience, to which we have gotten accustomed, and which is so much nicer than the LMS experience. I want to have my cake and eat it too!
  11. Further squeezelite tuning based on listening impressions Picking up where @ray-dude left off, I decided to play some more with the ALSA settings (-a). I started with my current settings for buffers and ALSA: -b 2097152:2097152 -a 16:4:: As we now know, the -a setting is a 4-tuple, where the first value represents the ALSA buffer in ms until a value of 499, after which it switches units to bytes. I first tried setting this buffer to 1 million bytes, (-a 1000000) where Ray had left off.This was definitely an improvement. Continuing on, I tried: -a 10485760 (10MB) -a 20485760 (20MB) -a 52428800 (50MB) -a 104857600 (100MB) -a 209715200 (200MB) One interesting functional quirk is that the bigger the buffer, there is a noticeable lag between an action (play, stop, etc) and its effect. Cutting to the chase, I felt the winner was 50MB, -a 52428800. Going higher didn't give any further improvement, but became functionally awkward due to the lag in actions. Note, I was using a 24/192 track from Jazz at the Pawnshop whose file size was 490MB. So clearly it isn't necessary for the ALSA buffer to cache the entire song. For reference, here is my current parameters line from /etc/squeezelite.conf: OPTIONS="-n sq-NUC -o hw:CARD=Interface -b 2097152:2097152 -a 52428800:4:: -D" As a sanity check, I switched back to RoonBridge, and felt a profound sense of loss... of SQ. If only we could do this type of tuning in RoonBridge! I'm not enamored of the bugginess of the Roon-squeezelite combination, but the SQ difference, especially with a tuned config like above, is just startling.
  12. So true! If you leave it play through a track, or better yet, an album, it mostly works. Although even there, on occasion it seems to forget how to do gapless playback, which gets annoying with classical pieces. If you do want to switch mid-song, it helps to hit pause first, wait a spell, then play the next song. If you go full ADD on it, and start switching tracks and sample rate midstream - it will hurt you! Yes, it's still a construction zone! Hard hats mandatory.
  13. Quick update... like a moth drawn to the flame, I keep getting drawn back to running squeezelite with large buffers on my NUC as a Roon endpoint, because of the better SQ... and then I get burned when it starts misbehaving again. With somewhat wishful thinking, I switched over to Squeezelite-R2, in the hope it would be more stable. No such luck. When it works though ... aah!

    But Paul is the only Jaeger-Meister, though.
