    It’s a Pi3 + HiFi Berry Digi Pro. I’m using the coax output of the Pi to drive a Cambridge Audio Azure 851D DAC, which drives an Emotiva 2 channel power amp.

    The 198k file is a FLAC on a USB thumb drive that is plugged directly into the PI.

    I’ve been playing other ripped CDs since then with no issues. All of my media on the thumb drive is FLAC.

    I think Heiner (or possibly someone on the HiFi Berry site) may have suggested that the root cause for this could be a corrupted SD card.

    That would be a good explanation since after doing a complete reload everything worked as it should.

    After the reload I’ve made it a point to create a backup image of my SD card and saved it on an external drive. If the SD card gets corrupted again (probably happens very easily if the OS is not shutdown before disconnecting power) I should be able to just reload the image from the backup.

    Thanks Heiner, My „notes“ are in MS OneNote, but I can „print“ it to just about any format including PDF/word. What format(s) would work best and where should I send it?

    Unrelated… I have had very little luck searching through these forums. In fact the only way I’ve been able to find this post is through the email chain. Is there a post somewhere in these forums that can give me pointers on how to search and locate „favorited“ posts?

    Problem solved. Root cause unknown…

    For some reason I lost all audio output when all I changed (or so I thought) was disabled bluetooth and build-in audio at the same time.

    After numerous attempts to recover I ended up re-imaging max2play from scratch. Now my 192k flacs play at 192; 96 flac plays at 96; and tidal plays at 44.1. This is what I expected.

    I need to save a copy of this config before making any new changes.

    Sorry for not having a better solution than this.

    I will say it is much easier to config this the second time around than the first.

    I have fairly detailed notes, included screen captures…

    What audio output do you have selected in Audioplayer menu?

    It is set to Default: (Use HDMI if plugged). My assumption, which may very well be incorrect, is that this only applies to the RPi onboard output options, hdmi vs 3mm phone jack. I also assume this should not have any impact if the digi+ is processing the output. What is the „correct“ setting?

    Disabling bluetooth and Build-in audio were both tried without success. I’ll disable them again, since for all practical purposes I will probably never need either. It’s possible I tested them one at a time; perhaps the combo of them will matter.

    Your pointers to the sound optimiztion links lead me to a whole new world of info on amixer/alsamixer, etc.

    One of the gems out there is /var/lib/alsa/asound.state.

    Here’s the config for the hifiberry… does it look reasonable. To me it looks rather uninteresting, state.IQaudIODAC has 16 controls.

    state.sndrpihifiberry {
    control.1 {
    iface MIXER
    name ‚Tx Source‘
    value AIF
    comment {
    access ‚read write‘
    count 1
    item.0 ‚S/PDIF RX‘
    item.1 AIF

    I can test using a hard connection to the lan, but I’ll need to get a 40′ patch cord. Then deal with the wife.

    I guess this is how one learns…

    Hi all,

    I hope I’m not jacking this thread but it seems to be pretty close to the issue I am having.

    I have a RPi3, HiFiBerry digi+ pro, max2play/squeezelite. The bits are sent to a Cambridge Audio 851D DAC via coax. The DAC also doubles as a simple pre-amp, which drives an Emotiva 300w/ch power amp, which drives my old school but high quality Magnat Deltas.

    Both RCA/coax and the DAC support up to 192.

    My goal with the RPi rig was to replace my laptop that I used to stream Tidal and play my ripped CDs with Media Monkey. If Windows 10 didn’t decide to do a system update/patch, the virus scanner decided it was time to check the hard drive.

    This little device plays great… I can stream tidal (I have the premium/HIFI membership), I can play my ripped CDs (from a thumb drive!!! Love it!), and even have access to Internet Radio, which I didn’t think I would ever care about (not sure yet that I do but it does open doors to new material).

    The issue I’m having is at most my DAC reports 48khz bit rate, and that’s only when I send a 24/192 or 24/96 flac into it. Anything else, Tidal and my ripped CDs are all playing at 44.1. The ripped CDs make sense… that is the resolution of the data files.

    It’s entirely possible Tidal is only presenting 44.1 data files… Though when playing Tidal through my laptop via HDMI (out) into TosLink I was running at 96k. I’m not sure how that happened either.

    But why do my „test“ flacs at the higher resolutions play of 24/96 and 24/192 only play at 48k? I know the digi+ Pro has two clocks… 44.1 and 48… is it just a coincidence that those are the only two resolutions I can get?

    I’ve done the usual checks… upgraded SqueezeLite, max2play, linux kernel… which I believe were all current as this is a brand new installation.

    I’ve poked around every menu in the Squeezebox „Settings“… tried a few interesting switches, but so far nothing seems to have an impact (sorry for the vagueness… I don’t have access to the SB menus right now). Changes that had no impact got rolled back to the default setting after testing.

    I have not tried to use the TosLink… but the resolution of the optical is less than the coax.

    Since this is a headless unit, I reduced the graphics processing unit from 128M to 16M… no impact, but it was worth a try.

    As far as I can tell this little machine is barely working. CPU utilization is single digits… the 32GB SD card is 95 percent free space.

    I am steaming the music over a wireless connection; the RPi is not hard wired into the LAN. That doesn’t seem to be a factor since I seldom (not always) get a pause in the audio as the download needs to catch up.

    In general this system sounds great… I’m just not 100 percent sure I have everything 100 percent correct.

    Thanks in advance for any suggestions!
