From: 이승빈 <mailto:seungbin.lee@samsung.com> Sent: Thursday, June 19, 2025 10:25 AM To: 'tiwai(a)suse.de' <mailto:tiwai@suse.de> Subject: [PATCH] ASoC: soc-compress: Fix race condition in soc_compr_open_fe Hi I am sending this email to report an issue found in sound/soc/soc-compress.c. Scenario: Playing a mix of MP3 and WAV files repeatedly from YouTube Music by pressing "next". Issue occurs when snd_soc_dpcm_runtime_update is called and soc_compr_trigger_fe is invoked, causing the value of “fe->dpcm[stream].runtime_update” to change mid-process. This results in a problem where, during the closing of the BE connected to the FE in snd_soc_dpcm_runtime_update, only the entry is removed from the list without actually being closed. The attached patch resolves this issue as confirmed through testing. Additionally, while performing DPCM related operations in soc-compress.c, snd_soc_dpcm_mutex_lock is used; however, soc_compr_trigger_fe does not have this lock. Please review the attached patch regarding this matter. Thank you. From 72a0340bf7dccc6f53dc2d02e04bb3f894d796e3 Mon Sep 17 00:00:00 2001 From: Seungbin Lee <mailto:seungbin.lee@samsung.com> Date: Wed, 18 Jun 2025 13:33:02 +0900 Subject: [PATCH] ASoC: soc-compress: Fix race condition in soc_compr_open_fe If the soc_compr_trigger_fe function is called during snd_soc_dpcm_runtime_update execution, the FE's DPCM runtime update variable may be changed. Then the BE list connected to the FE flies away, and the BE cannot be closed. This needs to be protected by the snd_soc_dpcm_mutex_lock.

[PATCH] ASoC: amd: ps: fix for soundwire failures during hibernation exit sequence
by Vijendar Mukunda 21 Jun '25

21 Jun '25

During the hibernate entry sequence, ACP registers will be reset to default values and acp ip will be completely powered off including acp SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable register is not restored along with pad pulldown control register value, then SoundWire manager links won't be powered on correctly results in peripheral register access failures and completely audio function is broken. Add code to store the acp SoundWire pad keeper enable register and acp pad pulldown ctrl register values before entering into suspend state and restore the register values during resume sequence based on condition check for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1 platforms.

Handling Lost Audio IRQs in ALSA: Triggering XRUN on Timer Detection?
by Verma, Sandeep 20 Jun '25

20 Jun '25

Hi all, I’m currently investigating a sporadic issue in our system where an audio interrupt is occasionally lost. When this happens, ALSA detects the anomaly (presumably through its internal timestamp or delay detection), but it doesn’t appear to take corrective action—leading to persistent audio jitter afterward. To address this, I’m considering implementing a mechanism in our driver or platform layer that uses a timer to check if the expected audio interrupt hasn’t arrived within a certain timeframe (e.g., 2x the period size). If this condition is met, I plan to explicitly trigger an XRUN to reset the pipeline and recover cleanly. My questions are: a. Is this an acceptable and “ALSA-friendly” way to handle lost IRQs? b. If this is a reasonable approach, why doesn’t ALSA do this by default? c. Is there a better or recommended way within the ALSA framework to detect and recover from such missed interrupts? I’d appreciate any guidance or suggestions. If this kind of timer-based recovery would be broadly useful, I’d also be happy to explore whether it could be proposed upstream. Thanks, Sandeep
