I have been using a USBridge (allo) for a long time now)
recently I have had my Sample rate locked to 48k While using Audirvana from PC. As well as when I use Mconnect from my phone.

The issue is consistent weather using qobuz or local files.
Neither limiting to 44.1k nor upsampling in Audirvana change the sample rate displayed , stuck at 48k
the output signal in the Audirvana App shows the proper Sample sample 41/96/192 etc..

However, when using Hqplayer. I can successfully Change sample rates.

I am starting to think, it maybe an MPD or GMrender issue. I do NOT have the ALLO gui. Is their a specific string I can input into my dietpi from putty.

looking to view / editing those audio render settings. to allow maximum / whatever the file played is natively

You are accessing the audio device via MPD? In the past we did, but do not hardcode the sample rate (or other audio format parameters) in /etc/mpd.conf anymore. The stream is just forwarded to the default ALSA PCM as received from the player, and that one, as defined in /etc/asound.conf, does not hardcode the format either.

But the MPD audio format can be changed (or reset) via dietpi-justboom. Probably you did it that way?

Not sure then. At some point, Allo stopped building these ASIX Ethernet driver for the USBridge Sig, hence now the upstream driver is used which can cause flickers in audio playback: raspberrypi/linux#2942

But the audio driver itself AFAIK has no changed. Can you show your MPD and ALSA config?

cat /etc/asound.conf
cat /etc/mpd.conf

GMediaRender is not related to MPD, but accesses audio devices directly in its own way. /etc/default/gmediarender defines the used ALSA PCM, which is just default by default, as defined in /etc/asound.conf.

the sample rate displayed , stuck at 48k
the output signal in the Audirvana App shows the proper Sample sample 41/96/192 etc..

Where do you see this 48k displayed? So you mean you can define the output signal in players, but at the server/hardware side you see 48k, when doing playback via GMediaRender or MPD, and only higher sample rates when using HQPlayer?

And does it work to enforce a sample rate via e.g.

speaker-test -r 192000

# This setting sets the MPD internal playlist directory. The purpose of this

It seems there has been no (default) sound card selected. Please try to select it in dietpi-config > Audio Options > Sound card.

ALSA else uses internal defaults, as shown in aplay -L (default and sysdefault), but those might imply auto-conversion and stuff like that. Selecting a sound card via dietpi-config (and leaving "auto-conversion" "off") creates a /etc/asound.conf which assures plain input stream playback without any ALSA plugin manipulation. If would then throw an error if the audio format is not supported by the sound card/driver, instead of trying (or doing OOTB) any conversion.

Does it matter which one I choose, I'm on an allo usbridge signature.

It matters in how far ALSA plugins are used, and e.g. it is possible that currently the RPi onboard audio is enabled and used as default ALSA PCM. The USBridge Sig audio device should show up at the bottom of the list in the "Auto detection" section, though I am not sure how exactly it is named.

Weird, can you copy&paste the full output of the log/console, after selecting hw:0,0 and exiting dietpi-config?

  1. Open dietpi-config audio options
  2. Select hw:0,0 as sound card
  3. Regardless what happens, go back and exit dietpi-config
  4. Select for copy&paste here all output done by dietpi-config

I eventually cycled through again. choose HW. and after it installed and asked to Me select a sound card. this time instead of saying None as usual.
I also went into volume mixer levels for ASLA MPD and then pressed f6 to choose sound card where i selected my holo audio.
then instead of hitting OK at the dietpi - config menu i hit exit . then used command reboot
seems to have fixed my issues :)

Hmm, there should not be a "none" option in the sound card menu. The only way to trigger this

[ SUB1 ] DietPi-Set_hardware > soundcard (none)

is to select "Disable" in the main audio menu. So I guess you selected "Ok", while "Disable" was highlighted, expecting this means to confirm/finish audio options, while instead the "Ok" button confirms the selection of the currently highlighted menu entry. "Back" or "Exit", i.e. the buttons on the right side, or hitting ESC key, would be the way to go.

A case where indeed the button text is misleading. In those whiptail menus, the button on the left side is equal to hitting enter/return while navigating the menu itself. We really need to adjust the button texts to better represent what they actually mean. In case of those menus, where you can navigate through the menu entries and hit enter/return, while you can also select the left button instead, it would be actually best to just hide the button. Sadly only the cancel button can be hidden.

However, glad it was sorted. So this means you can now effectively play audio with all sample rates through the USBridge Sig?

Okay great. I am happy that the driver is not broken 🙂. I'll mark the issue as closed then. Feel free to reopen if required.
