Y2Linux 1.0 Beta 8.21

Y2Linux 1.0 Beta 8.21: headphones on players with a slow DAC crystal. Linux 6.18 and the native Reborn music player for the Innioasis Y2.

Already running Y2Linux

Settings → About & Updates → Check for Updates → Update Now.

What's fixed

• Headphones: "Playback could not start" / "ALSA -110: Connection timed out" (#52, #54). On some players the headphone DAC's crystal takes longer to start than Y2Linux allowed. The stock firmware simply starts the crystal when the DAC powers on and never checks it; Y2Linux only started it when a song opened, gave up after a fraction of a second and restarted it from scratch on every retry, so a slow crystal never got going. The crystal now runs like on stock: it starts when the DAC powers on, keeps running until the DAC powers off, and a song waits up to 1 s for it and then plays anyway. Skipping tracks no longer restarts it. Beta 8.20's stronger crystal drive is gone (it did not help).
• The DAC now stays powered for 5 s after a song stops, so track changes don't restart it.
• Error reports show the crystal's state (ready, unconfirmed starts, errors).

If you had #52 or #54: please update and send a report after playing for a while, whether it works or not.

Everything from Beta 8.20 is included.

Install (from stock)

You need SP Flash Tool v5.2032, a USB cable, Y2Linux-1.0.0-beta.8.21-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)

• Some car radios don't show the song and artist yet; we are looking into it.
• In a very long single-file book, jumping to another chapter takes 2–3 seconds.
• The highest volume is still lower than stock's, even at High; demanding headphones may want more.
• The restart fix of Beta 8.4 is not yet confirmed over many restarts. If the screen ever stays dark, hold Power for 10 s and start again.
• Without Wi-Fi the clock starts at the release's build time after every restart and cannot be set by hand yet (#53).
• Battery life in sleep is not yet stock-like (about 8 mA vs stock 1.3 mA; some players draw more, #42).
• GC9503V players keep the old screen-off behaviour until a GC9503V owner has confirmed the new sequence (#45).
• The charging fix (#47) is not yet confirmed on an affected player; if yours still doesn't charge, please send a report.
• The player cannot detect wired headphones yet; the jack plays whenever no Bluetooth headphones are connected.
• BBC radio stations stream only in HLS, which the player does not play yet (planned for a later beta).
• FM radio is in the works for a later beta.
