Portable audio

Thanks Mike! I'll have to dig my Oppo HA-2 and OTG cable out again to mess with this. In the past, I think all I could get to work on the Oppo was UAPP (all these acronyms are killing me!), which limited playback to stored rips only.

Now it sounded great doing that, but I really like exploring new music on Spotify and radio paradise by downloading playlists and listening to them while walking, in the car or in the yard, which means the analog out (or even Bluetooth to a portable speaker) - or so I thought!

I remember when you first had trouble in getting other apps to work, and though I'm not sure that you still have that same phone anymore, I am relatively sure the problem you had was caused by the UAPP app hogging exclusive access to the DAC.

You will have to undo that permission if still in place, as well as ensure the MTP protocol is selected for USB configuration in Developer Options, or wherever your phone/Android version has such settings.

Pro tip: enabling the Developer Options in Android is not the exact same process for every phone model, so if they aren't already enabled, do a Google search on Developer Options specific to your device's model name/# to see how it's done.
 
In an example of "better late than never", Android 14 will offer support for native lossless audio, bypassing the existing Android audio stack and it's mandatory resampling.

Previously this was only possible with a handful of apps that utilized their own custom audio driver, most notably USB Audio Player Pro (UAPP). Starting with the Pixel 8 Series, Android 14 will offer a bit perfect audio path for use with any app, though that will require those apps to be updated to allow native bit perfect/lossless playback, either through wired headphones if the phone actually still has that jack (the Pixel does not), or an external DAC connected via USB.

Interesting timing on this, I bet it has at least something to do with Spotify Supremium's imminent availability.

I am currently running a pixel 6 with uapp. This might be the first phone I upgrade to on purpose. Thanks for the heads up
 
If it's in Android 14 (I'm already updated), I don't see why it would be device-specific unless there's some new chip inside that they're using. I'll keep an eye on this over the coming months as many things that start in the shiny new phones often makes its way down to the other phones in the lineup within months.

I probably use audio on the phone maybe once every two or three years, so it's no big deal to me. I've always used USB Audio Player Pro anyway and I have no reason to change that. Most of the time now, I'm using Bluetooth to send music to a JBL Boombox or a Scosche speaker for the bike. Or when I go shopping, the noise-cancelling earbuds via Bluetooth so I can drown out the horrid in-store music... 😁

Just an app-specific update based on the new API according to that article.

Me neither, but many others scream bloody murder and want only to use the native app versions for some reason, particularly so in the case of Spotify.

You and seemingly 99% of all people. I'm in the 1% club, I want high quality sound even in portable use cases, and it was never that tricky or expensive to achieve that, but now it will certainly be easier unless iOS is your daily driver.
 
I'm not too fussy with portable anymore. With the earbuds, I turn on the noise canceling and play quiet music in the background. If there were issues, I'd never hear them. On a boombox or portable speaker, there's so much ambient noise that any issues again I won't hear. I do have lossless in the car via the Pioneer head unit, which is convenient because I can copy files straight from the NAS to an SD card or thumb drive and not have to do any conversions.

I can understand a Qobuz user wanting a lossless option though, without having to mess with third party apps.
 


This little unit is currently launching on IGG at $129, however I'll skip the crowdfunding stage and wait for it to be a real/available product, expected to retail for $199.
  • 32-bit/768kHz PCM, and DSD256 too from the AKM AK4377ECB chipset, in the tiniest form factor you'll likely see at just 27.7mm long, 10.1mm thick, and 12.4mm wide.
  • 150+ mW RMS/channel stereo amp – over 300 mW RMS total output power into 32 Ohms.
  • 7 stage power supply, regulating and filtering each and every power rail – analog AND digital – to less than 3 microvolts of noise.
