You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

SplitPCM devices missing profiles since 1.2.10
by GitHub issues - edited 05 Jan '24

05 Jan '24

alsa-project/alsa-ucm-conf issue #346 was edited from freswa: When updating t 1.2.10 the profile `Analog Stereo Output + Inputs` is gone. Instead I get a `Surround ...` profile, which doesn't work at all. Downgrading alsa, alsa-ucm-conf and alsa-lib from 1.2.10 to 1.2.9 fixes the issue. I'm on Kernel 6.5.1 with Pipewire backend.

Intel audio controller: Loss of HDMI output between kernel versions
by Joel Roth 04 Jan '24

04 Jan '24

Will be grateful for any suggestions. My soundcard as reported by lspci: 00:1f.3 Audio device: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 30) I use the asoundrc below to route audio to both the analog output and the HDMI connector. With Debian kernel 6.0.0-6-amd64 I get sound at both outputs. With version 6.0.1-10-amd64 there is no HDMI output. pcm.hdmi_out { type hw card 0 device 7 } pcm.analog { type hw card 0 device 0 } pcm.hdmi_dmix { type dmix ipc_key 1024 ipc_perm 0666 # allow other users slave.pcm "hdmi_out" slave { period_time 0 period_size 1024 buffer_size 4096 channels 2 # must match bindings } bindings { 0 0 1 1 } } pcm.analog_dmix { type dmix ipc_key 2048 ipc_perm 0666 # allow other users slave.pcm "analog" slave { period_time 0 period_size 1024 buffer_size 4096 channels 2 # must match bindings } bindings { 0 0 1 1 } } pcm.!default { type asym playback.pcm "out" } # Multi pcm.out { type plug slave.pcm { type multi slaves { a { channels 2 pcm hdmi_dmix } b { channels 2 pcm analog_dmix } } bindings { 0 { slave a channel 0 } 1 { slave a channel 1 } 2 { slave b channel 0 } 3 { slave b channel 1 } } } ttable [ [ 1 0 1 0 ] # left -> a.left, b.left [ 0 1 0 1 ] # right -> a.right, b.right ] } -- Joel Roth

Regression in Final Scratch 'ScratchAmp' quirk (DJ interface)
by Mark Hills 04 Jan '24

04 Jan '24

The ScratchAmp worked perfectly with a quirk, but now that seems to have regressed and the device is no longer detected [1]. It's design is from 2002, based on class-compliant (Philips UDA1325H) chips. It hides itself behind a 'vendor specific' description, presumably as it was launched in a closed system with specific hardware and software for DJ'ing. So this quirk was introduced in 2007: +/* Stanton/N2IT Final Scratch v1 device ('Scratchamp') */ +{ + USB_DEVICE(0x103d, 0x0100), + .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { + .vendor_name = "Stanton", + .product_name = "ScratchAmp", + .ifnum = QUIRK_NO_INTERFACE + } +}, +{ + USB_DEVICE(0x103d, 0x0101), + .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { + .vendor_name = "Stanton", + .product_name = "ScratchAmp", + .ifnum = QUIRK_NO_INTERFACE + } +}, In a modern kernel, the (ineffective) quirk is now in sound/usb/card.c: + /* Stanton/N2IT Final Scratch v1 device ('Scratchamp') */ + DEVICE_NAME(0x103d, 0x0100, "Stanton", "ScratchAmp"), + DEVICE_NAME(0x103d, 0x0101, "Stanton", "ScratchAmp"), Is there a functional difference between these quirks and/or any reason the device would no longer be detected? I noted the commits went via use of QUIRK_RENAME_DEVICE(), perhaps misleading the refactoring to assume the quirk was purely a rename. Below is an "lsusb" of the device, dated from 2008; I don't currently have access to my own device, or know exactly when this regressed.

Reverting that patch on > top of mainline fixes it. As I've been (and still am) off, I had too little time for taking a deeper look now, unfortunately. But my wild guess is that it's a NULL dereference of the hdac_hda_priv referred via hdac dev. If it's correct, a oneliner like below should work around the crash. Could you give it a try? thanks, Takashi -- 8< -- --- a/sound/soc/codecs/hdac_hda.c +++ b/sound/soc/codecs/hdac_hda.c @@ -630,7 +630,7 @@ static int hdac_hda_dev_probe(struct hdac_device *hdev) snd_hdac_ext_bus_link_get(hdev->bus, hlink); /* ASoC specific initialization */ - if (hda_pvt->need_display_power) + if (hda_pvt && hda_pvt->need_display_power) ret = devm_snd_soc_register_component(&hdev->dev, &hdac_hda_hdmi_codec, hdac_hda_hdmi_dais, ARRAY_SIZE(hdac_hda_hdmi_dais));

[PATCH] ALSA: hda: cs35l41: fix building without CONFIG_SPI
by Arnd Bergmann 03 Jan '24

03 Jan '24

From: Arnd Bergmann <arnd(a)arndb.de> When CONFIG_SPI is disabled, the driver produces unused-variable warning: sound/pci/hda/cs35l41_hda_property.c: In function 'generic_dsd_config': sound/pci/hda/cs35l41_hda_property.c:181:28: error: unused variable 'spi' [-Werror=unused-variable] 181 | struct spi_device *spi; | ^~~ sound/pci/hda/cs35l41_hda_property.c:180:27: error: unused variable 'cs_gpiod' [-Werror=unused-variable] 180 | struct gpio_desc *cs_gpiod; | ^~~~~~~~ Avoid these by turning the preprocessor contionals into equivalent C code, which also helps readability.
