Y2Linux 1.0 Beta 9.2.16: steadier Bluetooth sound. 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

  • Steadier Bluetooth, lower default rates (Y2Reborn #87): crackling and cut-outs on Sony WH-1000XM4 headphones came from AAC at 320 kbit/s while Wi-Fi was on; the Y2 has one antenna that Wi-Fi and Bluetooth share. AAC now runs at 220 kbit/s by default (was up to 320) and LDAC at 330 kbit/s (was 660).
  • An extra limit while Wi-Fi is on: AAC at most 192 kbit/s and SBC one step below its top quality as long as the Wi-Fi radio is on; the full rate returns when Wi-Fi goes off. It changes while the music plays, without a reconnect.
  • Auto picks AAC first, then aptX, then SBC; LDAC and aptX HD only when you choose them in the service menu.
  • Your chosen codec is used even when the headphones connect during playback (Y2Reborn #87): it is asked for again at the next pause instead of being dropped until the next reconnect.

Before release: the platform's full check, Reborn's workspace tests and the tests of the release images, with new tests for the Wi-Fi limit (AAC and SBC), the defaults, Auto's order and the codec retry. Not yet tried on a player: if Bluetooth sounds worse or behaves differently than in 9.2.15, please send an error report (Settings → System → Error Reports).

What changed and why, in plain words: Beta 9.2.16 report. Everything from Beta 9.2.15 is included (Beta 9.2.15 report).

Install (from stock)

You need SP Flash Tool v5.2032, a USB cable, Y2Linux-1.0.0-beta.9.2.16-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)

  • Everything listed for Beta 9.0 still applies. If anything behaves differently from 9.2.14, 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.
  • How loud the wheel click should be is a first guess; tell us if it is too loud or too soft.
  • BBC radio stations stream only in HLS, which the player does not play yet. FM radio is in the works for a later beta.
