--- Begin Message ---Package: src:linux Version: 6.1.124-1 Severity: important Dear Maintainer, * What led up to the situation? Number of Debian bookworm (stable) systems were upgraded to 6.1.0-30 as part of the 12.9 release. Upon reboot, Asterisk/app_rpt audo has a choppy pulse noise for any played audio. Asterisk/app_rpt uses the snd_pcm_oss module for USB device access. Example: https://www.youtube.com/watch?v=1NFvY0KV7-I Forum Thread: https://community.allstarlink.org/t/after-kernel-update-debian12-asl3-distortion-choppy-audio-on-simpleusb-tx-audio-especially-telemetry/22684/50 * What exactly did you do (or not do) that was effective (or ineffective)? Reverting the system to linux-images-6.1.0-28-amd64 * What was the outcome of this action? Audio works as expected. Reinstalling -29 or -30 leads the the same artifact. -- Package-specific info: ** Version: Linux version 6.1.0-30-amd64 (debian-ker...@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.124-1 (2025-01-12) ** Command line: BOOT_IMAGE=/vmlinuz-6.1.0-30-amd64 root=/dev/mapper/node480162--vg-root ro quiet ** Not tainted ** Kernel log: [ 3.710616] Intel(R) Wireless WiFi driver for Linux [ 3.710850] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002) [ 3.715903] input: Dell WMI hotkeys as /devices/platform/PNP0C14:00/wmi_bus/wmi_bus-PNP0C14:00/9DBB5994-A997-11DA-B012-B622A1EF5492/input/input20 [ 3.716999] iwlwifi 0000:01:00.0: firmware: direct-loading firmware iwlwifi-7265D-29.ucode [ 3.717017] iwlwifi 0000:01:00.0: Found debug destination: EXTERNAL_DRAM [ 3.717020] iwlwifi 0000:01:00.0: Found debug configuration: 0 [ 3.717266] iwlwifi 0000:01:00.0: loaded firmware version 29.4063824552.0 7265D-29.ucode op_mode iwlmvm [ 3.744426] RAPL PMU: API unit is 2^-32 Joules, 5 fixed counters, 655360 ms ovfl timer [ 3.744429] RAPL PMU: hw unit of domain pp0-core 2^-14 Joules [ 3.744431] RAPL PMU: hw unit of domain package 2^-14 Joules [ 3.744432] RAPL PMU: hw unit of domain dram 2^-14 Joules [ 3.744433] RAPL PMU: hw unit of domain pp1-gpu 2^-14 Joules [ 3.744434] RAPL PMU: hw unit of domain psys 2^-14 Joules [ 3.748102] usbcore: registered new interface driver snd-usb-audio [ 3.752397] iTCO_wdt iTCO_wdt: Found a Intel PCH TCO device (Version=4, TCOBASE=0x0400) [ 3.752583] iTCO_wdt iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0) [ 3.791360] cryptd: max_cpu_qlen set to 1000 [ 3.818299] snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) [ 3.854765] usb 1-5: Found UVC 1.00 device Integrated_Webcam_HD (0bda:58c2) [ 3.867005] intel_rapl_common: Found RAPL domain package [ 3.867009] intel_rapl_common: Found RAPL domain core [ 3.867011] intel_rapl_common: Found RAPL domain uncore [ 3.867012] intel_rapl_common: Found RAPL domain dram [ 3.867014] intel_rapl_common: Found RAPL domain psys [ 3.893071] input: Integrated_Webcam_HD: Integrate as /devices/pci0000:00/0000:00:14.0/usb1/1-5/1-5:1.0/input/input21 [ 3.894401] usbcore: registered new interface driver uvcvideo [ 3.907440] AVX2 version of gcm_enc/dec engaged.
