[PATCH v4 0/2] ASoC: nau8325: Modify driver code and dtschema.
by Seven Lee 25 Mar '24

25 Mar '24

Modify properties description and use standard units in dtschema. Change: V1 -> V2: - Revise the driver description part for the C++ comment. - In the nau8325_clkdet_put function, modify the max variable to hard code. - Removed "Clock Detection" switch control. - modify the "ALC Enable" switch name. - Revise the dtschema for "nuvoton,dac-vref". V2 -> V3: - Properties use standard unit suffixes. - Modify the enum definition. - Driver code should be used dev_dbg(). V3 -> V4: - Properties use standard unit suffixes. - Modify the enum definition.

[PATCH v3 00/32] spi: get rid of some legacy macros
by Uwe Kleine-König 25 Mar '24

25 Mar '24

Changes since v2 (https://lore.kernel.org/linux-spi/cover.1705944943.git.u.kleine-koenig@peng…): - Drop patch "mtd: rawnand: fsl_elbc: Let .probe retry if local bus is missing" which doesn't belong into this series. - Fix a build failure noticed by the kernel build bot in drivers/spi/spi-au1550.c. (I failed to catch this because this driver is mips only, but not enabled in a mips allmodconfig. That's a bit unfortunate, but not easily fixable.) - Add the Reviewed-by: and Acked-by: tags I received for v2. Mark already announced for v2 that he is willing to apply the whole series to his spi tree. Assuming no other show stoper are found in this v3, I assume that's the plan still for this series now.

[PATCH] amdtp-stream: Checking a variable for zero before dividing

The step variable is initialized to zero. It changes in the loop, but if it doesn’t change it will remain zero. The patch added a variable check.

Variable mclk-fs in ASoC audio cards?
by John Watts 22 Mar '24

22 Mar '24

Greetings fellow ALSAers :) Over the past month I have been working on a driver for the 8-channel TDM CS5368 audio codec. However I've run in to an interesting snag that seems to be an open problem. Let me explain. The audio codec generally runs at 8 channels of 32-bit data, so: MCLK = BCLK = LRCK * 256 However it is possible to read 4 or 2 channels instead: MCLK = BCLK = LRCK * 128 MCLK = BCLK = LRCK * 64 This trade-off allows avoiding high frequency clocking at the expense of a reduced channel count. From what I current see the way to indicate the multiplier here is using mclk-fs in the device tree, but this would mean effectively fixing the channel count in the device tree. I have searched around found someone has suggested mapping mclk-fs to rates here: https://lore.kernel.org/all/CAEnQRZDpJu27_pB=-ZYQjsNPC8eA4-Ur-36niT2hCosMWt… This functionality is somewhat adjacent to it, but I was wondering if it would be better to somehow factor dai-tdm-slot-* in to mclk-fs calculation. Perhaps mclk-fs could be divided by dai-tdm-slot-num then multiplied by slots? Has anyone hit this problem before? How did you solve it? John.

synaptics hi-res audio usb device duplex, usb bandwidth issues
by Ian Malone 21 Mar '24

21 Mar '24

Hi, In short I have a USB to 3.5mm adapter which seems not to work in duplex mode on USB2.0 systems, possibly due to a bandwidth calculation bug. This is an evolution of an issue I previously posted on the users list with no luck. I have an Anker USB-C to 3.5mm audio dongle (lsusb: Conexant Systems (Rockwell), Inc. Hi-Res Audio) which I've used for some time on my phone (Android with USB-3.2). On trying to use it with an older T420 laptop recently with only USB-2.0 ports I discovered it will not work in duplex mode. Input-only and output-only profiles work (tested recording and playback with audacity), but with duplex no sound is recorded (Fedora 39, pipewire). This is easily reproduced by looking at the pavucontrol volume monitor for Output Devices, if I switch the device to Analog or Digital Input in configuration then the Input Devices level monitor for it shows activity if I speak into or tap the microphone. With duplex selected there is no activity, the level monitor bar may or may not display. I can switch between the two behaviours by changing the profile. Various applications such as Audacity and Zoom appear to hang when accessing this microphone with the duplex profile set. I've used pipewire configuration to force the format to 16LE only (playback and recording), but this has not helped. In dmesg this error appears when this happens (microphone opened, for example by pavucontrol): [ 294.825544] usb 1-1.1: cannot submit urb 0, error -28: not enough bandwidth (T420, Fedora 39, kernel 6.7.5) The T420 has USB 2 Type A ports, so a Type C to Type A adapter is needed, but the problem is not limited to the T420 laptop. On an older Samsung Tablet (Tab-A 2019, USB-2.0 Type C, kernel 4.4.177) I've been able to test using Google Meet. Although there are no errors or freezing observed, in headphone mode over USB the headphone microphone is not being used and the tablet uses its onboard microphone instead (although headphones are selected and playback is over the headphones). Again, I can record (via voice recorder) from the headset microphone, just no duplex. Trying google meet on my phone (USB3.2) I do get duplex over the USB-3.5 adapter. On a newer laptop with USB-3.2 and a mix of type A and C ports I also get duplex (F37, kernel 6.5.12), however dmesg shows even here not all is well, using the type A and C ports on the side: [ 9172.326602] usb 3-1: new full-speed USB device number 6 using xhci_hcd [ 9172.490169] usb 3-1: New USB device found, idVendor=0572, idProduct=1b08, bcdDevice= 0.10 [ 9172.490174] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 9172.490177] usb 3-1: Product: Hi-Res Audio [ 9172.490178] usb 3-1: Manufacturer: Synaptics [ 9172.490180] usb 3-1: SerialNumber: 000000000000000000000000 [ 9172.683435] input: Synaptics Hi-Res Audio as /devices/pci0000:00/0000:00:08.1/0000:05:00.4/usb3/3-1/3-1:1.3/0003:0572:1B08.000A/input/input36 [ 9172.736025] hid-generic 0003:0572:1B08.000A: input,hidraw5: USB HID v1.11 Device [Synaptics Hi-Res Audio] on usb-0000:05:00.4-1/input3 [ 9173.386988] usb 3-1: Not enough bandwidth for new device state.

This seems like some kind of bandwidth calculation problem in snd_usb_audio. I've tried building a kernel and modifying various of the defines in sound/usb/card.h (currently MAX_PACKS 4 and MAX_PACKS_HS (MAX_PACKS * 4), compared to 6 and *8) but not hit on a winning formula yet. Is there any information I could collect to try to fix this? -- imalone

Internal speakers and headphone not working on Huawei notebook
by Jacek Blocki 20 Mar '24

Hello, I have Huawei notebook (KLVL-WXXW-PCB) with Ubuntu 22.04.3 LTS installed alongside Windows. In Ubuntu, neither internal speakers nor headphone jack work. I only see Dummy Output while trying to adjust volume, but sound works with external HDMI monitor. Internal speakers work with Windows, so I believe hardware is fine and kernel driver (snd_hda_intel?) needs to be modified to fix the problem. I have submitted Ubuntu bug report back in January, but nobody touched it. So I try this list hoping for better result. $ cat /proc/asound/cards 0 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xd03c0000 irq 64 1 [acp ]: acp - acp HUAWEI-KLVL_WXXW-M1010-KLVL_WXXW_PCB I run 6.5.0-26-generic kernel. Regards, Jacek Błocki
