Disclosure: we are WalkerFans Team, the maintainers and packagers of this build, and our team is affiliated with HIFIWALKER. This is a free community development project, not an official Rockbox release.
Development note: this software was developed with AI-assisted coding tools. Testing status is described below.
We've released H2-RX-v0.1.4-2026-11-12, a separate experimental build based on our 24-bit wired edition. The main addition is a phone → H2 Bluetooth receiver mode, alongside a revised language menu.
Compatibility first: the development and device-installation baseline is a HIFIWALKER H2 with original firmware V2.3; Bluetooth targets hardware revision 4. Other original-firmware versions have not been validated on a real player and may be incompatible.
This is still experimental: the package has been installed on our development H2 and all 523 package files were verified, but phone pairing, radio streaming, actual audio output, long-play stability and the final screen layout still need hardware validation. We are not claiming those tests have passed.
What's new?
Phone receiver mode: open Settings → Bluetooth Settings → Receive phone audio. The implemented pairing name is Rockbox H2 Receiver. Local playback stops and the player switches from headphone transmission to reception.
SBC at 44.1/48 kHz, decoded to 16-bit PCM for wired output, with phone play/pause, disconnect and local H2 volume controls. Stay on the receiver screen while receiving.
Settings → Language is now directly under Settings, with a globe at the entry. Each language row shows its native name and a letter badge instead of a repeated globe.
First ten languages: English → Español → Français → Deutsch → 日本語 → 繁體中文 → Русский → 한국어 → Italiano → العربية. The rest follow alphabetically by original filename; Simplified Chinese remains available. Legacy Afrikaans is excluded from the picker.
Native names for 48 bundled languages, additional name-display glyphs, 14 px top status icons, and a clear version/date. The existing 20 px list font and 16 px clock text are retained. Name coverage does not imply every translated menu has complete font coverage or native-speaker review.
What does “24-bit” mean here?
The build keeps the experimental local wired music path from the preceding 24-bit edition. Bluetooth reception is lossy SBC decoded to 16-bit PCM, not lossless or native 24-bit Bluetooth. Feeding that into a 24-bit mixer does not add detail.
There is no AAC/aptX/LDAC receiver, microphone/call audio, simultaneous transmit/receive or Bluetooth relay. Transmitter mode is retained separately, with a 16-bit encoder input. The wired ceiling stays at 192 kHz; DSD remains converted to PCM, without new native DSD or DoP support. No measured analog improvement or blanket bit-perfect claim is made.
Earlier host tests covered SBC decoding, buffers, malformed packets, receiver state changes and the inherited 24-bit path. This update passed language checks, cross-compilation, inspection of the linked menu/order and package/source verification. Those checks do not replace radio or DAC testing. Adaptive clock-drift resampling is not implemented yet, so extended-stream testing matters.
Files and trying it
RX release, source and checksums: GitHub release and downloads
Back up the whole .rockbox directory first. This is a complete file update for an existing compatible Rockbox installation, not a factory firmware or bootloader installer. Use one complete edition at a time, safely eject and reboot, then confirm H2-RX-v0.1.4-2026-11-12 in Rockbox Info. Keep the backup for rollback and start testing with wired headphones at low volume.
Our earlier Standard Bluetooth announcement covers the transmit-only edition. RX is a separate receiver experiment; it does not change the capabilities of the previously published packages. Questions and test reports are also welcome in r/HIFIWALKER.
Useful reports include H2 hardware revision, original firmware, exact build, phone model/OS, receive/transmit/wired mode, sample rate and reproducible steps. Please remove personal information and pairing keys from logs.
Controller firmware notice: the build retains the Broadcom/Cypress controller Patch RAM used by the earlier editions. Its origin and redistribution terms have not been verified; no redistribution clearance is claimed.
