Y2Linux 1.0 Beta 9.3.12: Bluetooth pauses and skips like a phone. Linux 6.18 and the native Reborn music player for the Innioasis Y2.

Already running Y2Linux

Settings → System → Software Update → Update Now (on Beta 9.2.8 and older: Settings → About & Updates → Check for Updates → Update Now).

What changed

Beta 9.3.7 kept a Bluetooth stream open while you paused, so that no headphones would be asked to stop and start. Phones never do that, and it caused three complaints at once: silence after a pause or after the second or third song (#89), the connection drop about 20 seconds into a pause (AirPods Pro), and Buds that "disconnected" a minute into a pause (#90, where the player had in fact gone to sleep). This release goes back to what phones and Beta 9.2.16 do.

  • Pause stops the stream, Play starts a new one. Headphones that went silent after a pause or a skip, and the drop 20 s into a pause, both came from a stream kept open without sound: the headphones run dry and some (AirPods) never recover until a new stream starts.
  • A track change no longer interrupts the stream. The old song's last fraction of a second plays out and the next follows without a gap; before, the stream stopped for about 60 ms per skip (#89: "the second song is laggy, the third plays without sound").
  • A paused player with Bluetooth headphones stays awake 15 minutes before it sleeps (#90). The hold was there since Beta 8.18 but counted from the first pause after boot, so a later pause slept after 60 s, and sleep ends the Bluetooth link.
  • No more connect/drop loop for headphones that connect with a different codec than the chosen one (Y2Reborn #94: Bose SoundLink Flex 2, Sony WF-C710N).

Before release: the platform's full check, Reborn's workspace tests (new ones for the paused-headset hold and the kept Bluetooth sink) and the 552 tests of the release images. On the developer's player with AirPods Pro: skips in a row and pauses of various lengths, all with sound afterwards. A capture of the previous test build showed the packets to the headphones running on without a gap at the skips and silence only after the pause/resume gaps, which is what settled the cause. Other headphones were not re-tested yet: if yours behave worse than in 9.3.7, please send an error report.

What changed and why, in plain words: Beta 9.3.12 report. Versions 9.3.8 to 9.3.11 were unpublished test builds; everything from Beta 9.3.7 is included (Beta 9.3.7 report).

Install (from stock)

You need SP Flash Tool v5.2032, a USB cable, Y2Linux-1.0.0-beta.9.3.12-first-install.zip below and the Innioasis Y2 firmware package v3.2.0 from Innioasis (only this version works; it is also your way back to stock).

  1. Unpack both.
  2. SP Flash Tool → Download Only → load MT6582_Android_scatter.txt from the Y2Linux zip. Exactly BOOTIMG, RECOVERY, ANDROID and USRDATA are ticked.
  3. Click Download and connect the switched-off Y2; wait for the green tick.
  4. Unplug and press Power: the player sets up its Internal Storage (a few seconds), then Y2Linux and Reborn start, music works.
  5. Connect the Y2 to the computer and copy (don't move) system.img from the Innioasis package into the Firmware folder on Internal Storage. The player takes the Wi-Fi/Bluetooth firmware from it and turns the radios on.

Known issues (beta)

  • After a sleep (a pause longer than 15 minutes, or the Power button) the Bluetooth link ends; the player reconnects within a few seconds of waking. Buds that have gone back to a phone meanwhile must be picked again in Settings → Bluetooth.
  • The Hisense soundbar of Y2Reborn #94 (SBC only, connected but silent) is not resolved; try SBC quality High.
  • Everything listed for Beta 9.0 still applies. If anything behaves differently from 9.3.7, send an error report (Settings → System → Error Reports); Restore Previous System (Settings → System → About, tap Version seven times, then Diagnostics) goes back to the version you had, with your data kept.
  • Battery life in sleep: about 2 mA overnight on the developer's player (estimated from the battery voltage); stock is about 1.3 mA.
  • Some players turned off by themselves during playback; the cause is not found yet. If yours does, start it again and send a report.
  • The speaker uses the same volume as the headphones; its loudest step is the stock speaker's. Start low the first time.
  • BBC radio stations stream only in HLS, which the player does not play yet. FM radio is in the works for a later beta.
