Y2Linux 1.0 Beta 9.3.7

Y2Linux 1.0 Beta 9.3.7: Bluetooth rebuilt for reliability. 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

Bluetooth used to be handled by five separate pieces that coordinated through lock files; when two acted at once, headphones stayed half connected or reconnects stalled. One radio program now owns Bluetooth and the radio it shares with Wi-Fi. The player says what it wants, and the radio program gets there and repairs itself. Every codec, rate and quality setting from 9.2.16 is kept.

• Headphones come back after sleep, also when they reconnect by themselves: AirPods Pro were ready 2.5–5 s after a wake (before: often 15–20 s).
• Bluetooth repairs itself (cancel a stuck step, restart the radio, BlueALSA, BlueZ). If everything fails it says so: switching Bluetooth off and on in Settings now restarts all of Bluetooth.
• Connect Automatically per device (Y2Reborn #78): Settings → Bluetooth → a paired device.
• Codec and quality changes apply without restarting the player (the headphones are back in about 7–9 s).
• Your library is no longer emptied when a Bluetooth output fails (Y2Reborn #92).
• Headphones that are switched off are no longer paged forever; pausing keeps the connection instead of stopping the stream; Wi-Fi uses its power saving while Bluetooth plays; after sleep Wi-Fi waits for your headphones; each pair of headphones starts at the rate it managed last time.

Before release: the platform's full check, Reborn's workspace tests, the 552 tests of the release images, and a fake Bluetooth stack with six failure scenarios. On the developer's player with AirPods Pro: 19 sleep/wake cycles without a failed connection. Only AirPods Pro were tried, and there is no overnight run on this exact build yet: if your headphones behave worse than in 9.2.16, please send an error report.

What changed and why, in plain words: Beta 9.3.7 report. Versions 9.3 to 9.3.6 were unpublished test builds; everything from Beta 9.2.16 is included (Beta 9.2.16 report).

Install (from stock)

You need SP Flash Tool v5.2032, a USB cable, Y2Linux-1.0.0-beta.9.3.7-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)

• Bluetooth after a long pause: with AirPods Pro, a pause longer than about 20 seconds drops the connection once; they reconnect within seconds, but pressing play during those 20 seconds can stay silent until they are back. Being investigated.
• Everything listed for Beta 9.0 still applies. If anything behaves differently from 9.2.16, 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.
