From a0f7989d3a2b443f630d02ec7e535b22b95521ce Mon Sep 17 00:00:00 2001 From: root Date: Sat, 8 Nov 2025 14:43:48 +0300 Subject: [PATCH 01/18] Fix MCLKOUT clock routing for kernel 6.1 audio artifacts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: Audio artifacts/distortion on 44.1 kHz sample rate family due to MCLKOUT stuck at 12 MHz instead of following calibrated PLL frequencies. Root cause: Clock multiplexer CLK_I2S0_8CH_TX was not being switched to CLK_I2S0_8CH_TX_SRC parent at boot, remaining on default xin_osc0_half (12 MHz). Solution: - Add CLK_I2S0_8CH_TX to assigned-clocks with parent CLK_I2S0_8CH_TX_SRC - Add I2S0_8CH_MCLKOUT to assigned-clocks with parent MCLK_I2S0_8CH_TX - Add rockchip,no-fractional-divider property to prevent fractional divider selection - Remove MCLKOUT management from driver (managed via device tree only) Clock path now matches kernel 5.10 behavior: PLL_GPLL → TX_SRC (calibrated) → CLK_TX → MCLK_TX → MCLKOUT Verified working: - 44.1 kHz → MCLKOUT = 45.158 MHz ✓ - 48 kHz → MCLKOUT = 49.152 MHz ✓ - 88.2/96/192 kHz all working correctly ✓ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- ext_tree/board/luckfox/config/linux.config | 1297 ++++-- .../board/luckfox/dts_max/rv1106_pll-ipc.dtsi | 12 +- ext_tree/board/luckfox/scripts/post-build.sh | 2 +- ext_tree/patches/linux_rv1106.patch | 3906 +++++++++++------ 4 files changed, 3473 insertions(+), 1744 deletions(-) diff --git a/ext_tree/board/luckfox/config/linux.config b/ext_tree/board/luckfox/config/linux.config index 5e176abd..af73fb9e 100644 --- a/ext_tree/board/luckfox/config/linux.config +++ b/ext_tree/board/luckfox/config/linux.config @@ -1,21 +1,26 @@ #

Fixed PCM noise in EXT mode by preventing DSD routing from affecting PCM data 2. Updated I2S driver with extensive debugging and clock handling improvements 3. Modified kernel configuration and patches for proper audio support Key fix: Modified rockchip_i2s_tdm_handle_dsd_switch() to apply DSD routing only when DSD is being enabled, preventing PCM channel corruption in EXT mode. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../sound/soc/rockchip/rockchip_i2s_tdm.c | 3897 +++++++++++++++++ ext_tree/board/luckfox/config/linux.config | 134 +- ext_tree/patches/linux_rv1106.patch | 12 +- 3 files changed, 3935 insertions(+), 108 deletions(-) create mode 100644 buildroot/output/build/linux-custom/sound/soc/rockchip/rockchip_i2s_tdm.c diff --git a/buildroot/output/build/linux-custom/sound/soc/rockchip/rockchip_i2s_tdm.c b/buildroot/output/build/linux-custom/sound/soc/rockchip/rockchip_i2s_tdm.c new file mode 100644 index 00000000..6d32d66c --- /dev/null +++ b/buildroot/output/build/linux-custom/sound/soc/rockchip/rockchip_i2s_tdm.c @@ -0,0 +1,3897 @@ +/* sound/soc/rockchip/rockchip_i2s_tdm.c + * + * ALSA SoC Audio Layer - Rockchip I2S/TDM Controller driver + * + * Copyright (c) 2018 Rockchip Electronics Co.

mode switching - Add USBtoI2S button to web interface with unique purple style - Implement USB mode switching via web (host/gadget) - Remove usb-mode-switch script - not needed anymore - Add S00usbmodules init script to load USB modules on boot based on mode - Update post-build.sh to strip and remove duplicate external toolchain libraries (libstdc++, libgcc_s, libatomic, libgfortran, libgomp) - saves ~28MB - Add uac2_router package with S98uac2 for UAC2 gadget management - Update ALSA scripts to properly stop services using sh -c '/etc/init.d/S95*' - Fix I2S TDM DSD routing and BCLK calculation for UAC2 router - Add dwc3_gadget.ko custom module for USB gadget mode - Add dwc3_host.ko custom module for USB host mode - Use standard dwc3-of-simple.ko from kernel for both modes - Add USBtoI2S state file persistence across reboots - Web button shows loading spinner and locks/unlocks USB-I2S toggle - Button stays active after enable and deactivates on player switch - USB modules load based on /etc/usb_to_i2s.state file at boot - Fix external toolchain library duplication issue in /lib and /usr/lib --- .gitignore | 1 + .../board/luckfox-pico/common/linux.config | 1 +

From 785691fe144884135bb30f7affd7cbff8df392bf Mon Sep 17 00:00:00 2001 From: root Date: Thu, 26 Feb 2026 05:36:41 +0100 Subject: [PATCH 14/18] fix: correct DSD BCLK calculation (kHz -> MHz) calculate_dsd_bclk() was returning raw sample_rate (~88-706 kHz) instead of the actual DSD bit clock. Roon passes PCM-equivalent sample rates via uac2_router, not native DSD bit rates. BCLK = sample_rate * bits_per_word: DSD_U32_LE: 88200 * 32 = 2,822,400 Hz (DSD64) DSD_U32_LE: 176400 * 32 = 5,644,800 Hz (DSD128) DSD_U32_LE: 352800 * 32 = 11,289,600 Hz (DSD256) DSD_U32_LE: 705600 * 32 = 22,579,200 Hz (DSD512) Without this fix div_bclk was computed as ~256 instead of ~8, resulting in BCLK ~256x too slow and completely wrong I2S timing in DSD mode.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two fixes for DSD frequencies in the 48kHz family (DSD64/48=3.072MHz, DSD128/48=6.144MHz, etc.): 1. div_lrck is now derived from DSD format word size, not hardcoded to 32. Relationship: LRCK = BCLK / div_lrck = sample_rate, so div_lrck = bits_per_word: DSD_U8: div_lrck = 8 DSD_U16_LE/BE: div_lrck = 16 DSD_U32_LE/BE: div_lrck = 32 (unchanged, primary Roon format) 2. Expected MCLK check now accounts for both frequency families and mclk_multiplier: 44.1kHz grid: 22,579,200 Hz (x512) / 45,158,400 Hz (x1024) 48kHz grid: 24,576,000 Hz (x512) / 49,152,000 Hz (x1024) Previously the check was hardcoded to 22,579,200 Hz only, producing false warnings for every 48kHz DSD stream. Note: calculate_dsd_bclk (sample_rate * bits_per_word) is already correct for 48kHz grid — no changes needed there.

Previous 3 commits (785691fe, 9c0a7051, part of 979e01fd) incorrectly modified it directly. All changes are now applied to the proper location: ext_tree/patches/linux_rv1106.patch. linux_rv1106.patch — calculate_dsd_bclk(): Two-convention DSD BCLK calculation: A) uac2_router: native DSD rate >= 1 MHz -> BCLK = rate (as-is) B) Roon/ALSA: PCM frame rate < 1 MHz -> BCLK = rate * bits_per_word Handles both 44.1kHz and 48kHz DSD families. linux_rv1106.patch — DSD hw_params: - MCLK check accounts for both frequency families and mclk_multiplier (was hardcoded to 22579200 Hz, now derives expected value correctly) - div_lrck derived from format word size (U8=8, U16=16, U32=32) instead of hardcoded 32 — correct for all DSD format types uac2_router.c — already committed in 979e01fd, re-staged to confirm.
