stream == SND_PCM_STREAM_PLAYBACK ? _("underrun") : _("overrun"),
by sujith kumar reddy 15 Jul '22

Hi ALL, in the below link https://github.com/bear24rw/alsa-utils/blob/master/aplay/aplay.c#L1360 My question here is .. aplay -->writes the data from userspace to system dma (in the kernel alsabuffer).and from system dma to hardware dma(if hardware dma present)and to fifo. Now the application writes the data to system dma -->is always fast because the cpu runs in GHz. and from system dma to i2s fifo runs on i2s mclk.which is running on 196.6MHz. My point is.. cpu is always fast and controller is slow ,so when playback we should get overrun. the command should be like this in my point of you. stream == SND_PCM_STREAM_PLAYBACK ? : _("overrun") _("underrun"), Please let me know if I am wrong. Thanks Sujith

[PATCH] ASoC: mediatek: mt8195: extract SOF common code
by Chunxu Li 15 Jul '22

15 Jul '22

The functions related to SOF can be reused in different machine drivers, such as mt8195 or mt8186, so extract the common code to avoid duplication. Set mtk_soc_card_data which include machine private data and SOF private data as card drvdata, then the difference between machine private can be ignored such as mt8195_mt6359_priv or mt8186_mt6366_priv, at the same time the SOF related code can be reused in different machine drivers.

When the driver fails in snd_card_register() at probe time, it will free the 'bcd2k->midi_out_urb' before killing it, which may cause a UAF bug. The following log can reveal it: [ 50.727020] BUG: KASAN: use-after-free in bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000] [ 50.727623] Read of size 8 at addr ffff88810fab0e88 by task swapper/4/0 [ 50.729530] Call Trace: [ 50.732899] bcd2000_input_complete+0x1f1/0x2e0 [snd_bcd2000] Fix this by adding usb_kill_urb() before usb_free_urb().

The ES8326 codec is not compatible with ES8316 and requires a dedicated driver.

No Audio: MAG Z690 TOMAHAWK WIFI DDR4 & how to build info request
by GitHub issues - edited 14 Jul '22

14 Jul '22

alsa-project/alsa-ucm-conf issue #189 was edited from Dave--G: My MAG Z690 TOMAHAWK WIFI DDR4 motherboard has no alsa audio support. It looks like the realtek-alc4080 audio chip is supported, just not on this motherboard due to a missing entry in `USB-Audio.conf`. The USB audio device id is `0db0:b202`. Currently it just displays as `USB Audio` and doesn't function at all. This device works under windows so the hardware is functioning but no linux distro I've tried. I attempted to address this myself, by downloading `https://github.com/alsa-project/alsa-ucm-conf/releases/tag/v1.2.7.2`, copying it to `/usr/share/alsa` (preserving simlinks of course) and editing `ucm2/USB-Audio/USB-Audio.conf`, changing line 46 to read ` Regex "USB((0b05:(1996|1a2[07]))|(0db0:(1feb|419c|a073|b202)))"`. However, when I execute `sudo alsa force-reload` it generates parsing errors and `pactl list sinks` does not show any changes to the device properties as expected. Can someone please explain what I need to do to get this device working? Am I on the right track? Do I need to rebuild alsa from github? It's not clear and I'm not seeing build instructions. I've been struggling with this for quite some time so any help would be appreciated. I will PR the fix back to this repo once its working.

[PATCH] ASoC: rsnd: care default case on rsnd_ssiu_busif_err_irq_ctrl()
by Kuninori Morimoto 14 Jul '22

14 Jul '22

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Before, ssiu.c didn't care SSI5-8, thus, commit b1384d4c95088d0 ("ASoC: rsnd: care default case on rsnd_ssiu_busif_err_status_clear()") cares it for status clear. But we should care it for error irq handling, too. This patch cares it.

[PATCH v2] ASoC: SOF: ipc-msg-injector: fix copy in sof_msg_inject_ipc4_dfs_write()
by Dan Carpenter 14 Jul '22

14 Jul '22

There are two bugs that have to do with when we copy the payload: size = simple_write_to_buffer(ipc4_msg->data_ptr, priv->max_msg_size, ppos, buffer, count); The value of "*ppos" was supposed to be zero but it is sizeof(ipc4_msg->header_u64) so it will copy the data into the middle of the "ipc4_msg->data_ptr" buffer instead of to the start. The second problem is "buffer" should be "buffer + sizeof(ipc4_msg->header_u64)". This function is used for fuzz testing so the data is normally random and this bug likely does not affect anyone very much. In this context, it's simpler and more appropriate to use copy_from_user() instead of simple_write_to_buffer() so I have re-written the function.

[PATCH v9 0/8] ASoC: mediatek: Add support for MT8186 SoC
by Jiaxin Yu 14 Jul '22

14 Jul '22

This series of patches adds support for Mediatek AFE of MT8186 Soc. Patches are based on broonie tree "for-next" branch. Changes since v8: - Remove unnecessary comments and blank line. - Use devm_add_action_or_reset to ease error handling when dev probe. - Remove .remove callback in plaform driver. Changes since v7: - Optimize the code logic, such as the return value and position of a function. - Use devm_pm_runtime_enable() instead of pm_runtime_enable(). - Use pm_runtime_resume_and_get() instead of pm_runtime_get_sync(). Changes since v6: - The Makefile and Kconfig updates are moved into the driver patches so that can keep independence of each patch. Changes since v5: - fix build error about function snd_soc_card_jack_new that modified by: Link: https://lore.kernel.org/r/20220408041114.6024-1-akihiko.odaki@gmail.com - some have been accepted, details are in the link below: Link: https://lore.kernel.org/all/165459931885.399031.2621579592368573898.b4-ty@k… Changes since v4: - [v5 07/20] - remove unsusd controls - [v5 09/20] - correct indent error - [v5 10/20] - [v5 13/20] - [v5 14/20] - fix the return value if the value is different from the previous value in mixer controls - [v5 17/20] - [v5 19/20] - correct the compatible name with '_' instead of '-' - [v5 18/20] - [v5 20/20] - correct the yaml after 'pip3 install dtschema --upgrade' Changes since v3: - [v4 09/18] - remove DEBUG_COEFF debugging code - [v4 10/18] - simplify the logic of the code - [v4 13/18] - split out the MT6366 bits into mt8186-mt6366-commom.c - fix build error of "error: 'struct dev_pm_info' has no member named 'runtime_error'" - fix bug of adda dai driver - add route for pcm interface channel 2. - [v4 15/18] - [v4 17/18] - commonize the configuration of the codec - move MT6366 common bits into mt8186-mt6366-common.c Changes since v2: - add a new compatible string "mediatek,mt6366-sound" - modify the log level for simplicity - use dev_err_probe(...) instead of dev_err(...) in dev probe() - optimized the logic of some code - use BIT() and GENMASK() macros to descript the registers Thanks for AngeloGioacchino's careful reviews. Changes since v1: [v2 01/17] - add a new ID to the existing mt6358 codec driver [v2 03/17] - modify log level in DAPM events - use standard numeric control with name ending in Switch - return 1 when the value changed in mixer control's .get callback [v2 05/17] - ending in Switch to the standard on/off controls - change to "HW Gain 1 Volume" and "HW Gain 2 Volume" [v2 09/17] - return an error in the default case rather than just picking one of the behaviours when do .set_fmt - use the new defines that are _PROVIDER_MASK, _DAIFMT_CBP_CFP and _DAIFMT_CBC_CFC [v2 10/17] [v2 11/17] - the clock and gpio are aplit out into separate patches The source file's GPL comment use c++ style, and the header fils's GPL comment use c style. We have added "Switch" after the names of all the controls that just are simple on/off.

[PATCH 1/2] ASoC: codecs: add support for ES8326
by Zhu Ning 14 Jul '22

14 Jul '22

The ES8326 codec is not compatible with ES8316 and requires a dedicated driver.
