Logitech Z10 USB speakers need a volume change before audio works
by Hans de Goede 07 Dec '21

07 Dec '21

Hi, I've a set of Logitech Z10 USB speakers, which act as a USB soundcard. They have this weird glitch where after turning off my PC (and their power-supply as well) and then turning things back on, they are silent until I change the PCM volume control for the speakers inside alsa-mixer. It seems like they need some "set-volume" command to be send over the USB bus to unmute them when initially powered-up / turned on. Is their some existing usb-audio quirk which I can try to work around this? Regards, Hans

[PATCH] ALSA: mixart: Reduce size of mixart_timer_notify
by Kees Cook 07 Dec '21

07 Dec '21

The mixart_timer_notify structure was larger than could be represented by the mixart_msg_data array storage. Adjust the size to as large as possible to fix the warning seen with -Warray-bounds builds: sound/pci/mixart/mixart_core.c: In function 'snd_mixart_threaded_irq': sound/pci/mixart/mixart_core.c:447:50: error: array subscript 'struct mixart_timer_notify[0]' is partly outside array bounds of 'u32[128]' {aka 'unsigned int[128]'} [-Werror=array-bounds] 447 | for(i=0; i<notify->stream_count; i++) { | ^~ sound/pci/mixart/mixart_core.c:328:12: note: while referencing 'mixart_msg_data' 328 | static u32 mixart_msg_data[MSG_DEFAULT_SIZE / 4]; | ^~~~~~~~~~~~~~~ Signed-off-by: Kees Cook <keescook(a)chromium.org> --- sound/pci/mixart/mixart_core.c | 3 +-- sound/pci/mixart/mixart_core.h | 10 +++++++++- 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/sound/pci/mixart/mixart_core.c b/sound/pci/mixart/mixart_core.c index fb8895af0363..853083dd4bad 100644 --- a/sound/pci/mixart/mixart_core.c +++ b/sound/pci/mixart/mixart_core.c @@ -23,8 +23,6 @@ #define MSG_DESCRIPTOR_SIZE 0x24 #define MSG_HEADER_SIZE (MSG_DESCRIPTOR_SIZE + 4) -#define MSG_DEFAULT_SIZE 512 - #define MSG_TYPE_MASK 0x00000003 /* mask for following types */ #define MSG_TYPE_NOTIFY 0 /* embedded -> driver (only notification, do not get_msg() !) */ #define MSG_TYPE_COMMAND 1 /* driver <-> embedded (a command has no answer) */ @@ -444,6 +442,7 @@ irqreturn_t snd_mixart_threaded_irq(int irq, void *dev_id) struct mixart_timer_notify *notify; notify = (struct mixart_timer_notify *)mixart_msg_data; + BUILD_BUG_ON(sizeof(notify) > sizeof(mixart_msg_data)); for(i=0; i<notify->stream_count; i++) { u32 buffer_id = notify->streams[i].buffer_id; diff --git a/sound/pci/mixart/mixart_core.h b/sound/pci/mixart/mixart_core.h index fbf4731a276d..2f0e29ed5d63 100644 --- a/sound/pci/mixart/mixart_core.h +++ b/sound/pci/mixart/mixart_core.h @@ -49,6 +49,7 @@ enum mixart_message_id { MSG_CLOCK_SET_PROPERTIES = 0x200002, }; +#define MSG_DEFAULT_SIZE 512 struct mixart_msg { @@ -251,10 +252,17 @@ struct mixart_sample_pos u32 sample_pos_low_part; } __attribute__((packed)); +/* + * This structure is limited by the size of MSG_DEFAULT_SIZE.

I believe this is happening because the driver isn't being picked up, and plughw simply adds what it can to the device making it work. The end result is neither PipeWire or PluseAudio detect the speaker device, I assume this is because they're expecting to use the raw hw device handle Here's my ucm2 config: https://github.com/hexdump0815/imagebuilder/blob/d02a71ace7b93b8efbff842662… Any help would be appreciated, thank you

Support for 8086:ae20 Intel Smart Sound Technology on Fujitsu Lifebook
by Norbert Preining 07 Dec '21

07 Dec '21

Dear all, (please Cc) today I realized that the built-in microphone (next to the webcam) of my Fujitsu Lifebook U-series is not detected. (I usully use a headset, but due to travelling was forced to use the internal). I tried hard to get this device working, but neither with my self-compiled kernel (5.15.6) nor the Debian kernel distribution kernel 5.15 the microphone seems to be detected. I booted into Windows and tried to find out what the device might be. My **guess** is what is mentioned as Intel Smart Sound Technology with Vendor ID 8086 Device ID ae20 I git grepped the kernel sources for this, and snd-hda-intel contains quite some mentioning about Vendor ID 8086, but ae20 is not appearing. Now the interesting thing is that booting into linux and using lspci and lsusb, I cannot see a single device with the above specifications: lspci: root@sakefilet /usr/src/git/linux/Documentation # lspci 00:00.0 Host bridge: Intel Corporation Comet Lake-U v1 4c Host Bridge/DRAM Controller (rev 0c) 00:02.0 VGA compatible controller: Intel Corporation CometLake-U GT2 [UHD Graphics] (rev 02) 00:04.0 Signal processing controller: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal Subsystem (rev 0c) 00:12.0 Signal processing controller: Intel Corporation Comet Lake Thermal Subsytem 00:14.0 USB controller: Intel Corporation Comet Lake PCH-LP USB 3.1 xHCI Host Controller 00:14.2 RAM memory: Intel Corporation Comet Lake PCH-LP Shared SRAM 00:14.3 Network controller: Intel Corporation Comet Lake PCH-LP CNVi WiFi 00:15.0 Serial bus controller [0c80]: Intel Corporation Serial IO I2C Host Controller 00:15.1 Serial bus controller [0c80]: Intel Corporation Comet Lake Serial IO I2C Host Controller 00:15.3 Serial bus controller [0c80]: Intel Corporation Device 02eb 00:16.0 Communication controller: Intel Corporation Comet Lake Management Engine Interface 00:16.3 Serial controller: Intel Corporation Device 02e3 00:1c.0 PCI bridge: Intel Corporation Comet Lake PCI Express Root Port #1 (rev f0) 00:1c.4 PCI bridge: Intel Corporation Comet Lake PCI Express Root Port #5 (rev f0) 00:1d.0 PCI bridge: Intel Corporation Comet Lake PCI Express Root Port #9 (rev f0) 00:1d.4 PCI bridge: Intel Corporation Comet Lake PCI Express Root Port #13 (rev f0) 00:1e.0 Communication controller: Intel Corporation Device 02a8 00:1e.1 Communication controller: Intel Corporation Device 02a9 00:1f.0 ISA bridge: Intel Corporation Comet Lake PCH-LP LPC Premium Controller/eSPI Controller 00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH-LP cAVS 00:1f.4 SMBus: Intel Corporation Comet Lake PCH-LP SMBus Host Controller 00:1f.5 Serial bus controller [0c80]: Intel Corporation Comet Lake SPI (flash) Controller 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (10) I219-LM 06:00.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge 4C 2018] (rev 06) 07:00.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge 4C 2018] (rev 06) 07:01.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge 4C 2018] (rev 06) 07:02.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge 4C 2018] (rev 06) 07:04.0 PCI bridge: Intel Corporation JHL7540 Thunderbolt 3 Bridge [Titan Ridge 4C 2018] (rev 06) 08:00.0 System peripheral: Intel Corporation JHL7540 Thunderbolt 3 NHI [Titan Ridge 4C 2018] (rev 06) 3d:00.0 USB controller: Intel Corporation JHL7540 Thunderbolt 3 USB Controller [Titan Ridge 4C 2018] (rev 06) 72:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983 77:00.0 SD Host controller: O2 Micro, Inc.
