envy24control: fix memory access errors in profiles
by GitHub pull_request - opened 29 Mar '25

29 Mar '25

alsa-project/alsa-tools pull request #34 was opened from andreas56: Fix two memory errors in the profiles parser: an invalid read and a "source and destination overlap in strncpy" warning. When the profiles page is initialized it fetches the profile names from the profiles file. When a profile wasn't defined in the file, the parser made invalid reads outside the buffer.

[PATCH v1] ALSA: hda/tas2781: Upgrade calibratd-data writing code to support Alpha and Beta dsp firmware
by Shenghao Ding 28 Mar '25

28 Mar '25

Since 2025, the firmware for tas2781 has been added more audio acoustic features, such as non-linear compensation, advanced battery guard, rattle-noise suppression, etc. The version was divided into two different series. Both series have a slight change on the calibrated data storage addresses, which becames flexible instead of fixed. In order to support new firwmares in time, the code have some related upgrades. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- v2: - revise the subject and description. v1: - Add updating calibration addresses code into tas2781_apply_calib in case of Alpha and Beta firmware. --- sound/pci/hda/tas2781_hda_i2c.c | 30 ++++++++++++++++++++---------- 1 file changed, 20 insertions(+), 10 deletions(-) diff --git a/sound/pci/hda/tas2781_hda_i2c.c b/sound/pci/hda/tas2781_hda_i2c.c index 9ed49b0dbe6b..29dc4f500580 100644 --- a/sound/pci/hda/tas2781_hda_i2c.c +++ b/sound/pci/hda/tas2781_hda_i2c.c @@ -558,28 +558,38 @@ static int tas2563_save_calibration(struct tasdevice_priv *tas_priv) static void tas2781_apply_calib(struct tasdevice_priv *tas_priv) { - static const unsigned char page_array[CALIB_MAX] = { - 0x17, 0x18, 0x18, 0x13, 0x18, + struct calidata *cali_data = &tas_priv->cali_data; + struct cali_reg *r = &cali_data->cali_reg_array; + unsigned int cali_reg[CALIB_MAX] = { + TASDEVICE_REG(0, 0x17, 0x74), + TASDEVICE_REG(0, 0x18, 0x0c), + TASDEVICE_REG(0, 0x18, 0x14), + TASDEVICE_REG(0, 0x13, 0x70), + TASDEVICE_REG(0, 0x18, 0x7c), }; - static const unsigned char rgno_array[CALIB_MAX] = { - 0x74, 0x0c, 0x14, 0x70, 0x7c, - }; - int offset = 0; int i, j, rc; + int oft = 0; __be32 data; + if (tas_priv->dspbin_typ != TASDEV_BASIC) { + cali_reg[0] = r->r0_reg; + cali_reg[1] = r->invr0_reg; + cali_reg[2] = r->r0_low_reg; + cali_reg[3] = r->pow_reg; + cali_reg[4] = r->tlimit_reg; + } + for (i = 0; i < tas_priv->ndev; i++) { for (j = 0; j < CALIB_MAX; j++) { data = cpu_to_be32( - *(uint32_t *)&tas_priv->cali_data.data[offset]); + *(uint32_t *)&tas_priv->cali_data.data[oft]); rc = tasdevice_dev_bulk_write(tas_priv, i, - TASDEVICE_REG(0, page_array[j], rgno_array[j]), - (unsigned char *)&data, 4); + cali_reg[j], (unsigned char *)&data, 4); if (rc < 0) dev_err(tas_priv->dev, "chn %d calib %d bulk_wr err = %d\n", i, j, rc); - offset += 4; + oft += 4; } } } -- 2.34.1

[ alsa-lib ] OpenHarmony Adaptation Proposal
by GitHub issues - opened 28 Mar '25

28 Mar '25

alsa-project/alsa-lib issue #445 was opened from Asercn: # [ alsa-lib ] OpenHarmony Adaptation Proposal ## Background OpenHarmony is an open-source project incubated and operated by the OpenAtom Open Source Foundation. Its goal is to build an operating system framework and platform for intelligent terminal devices in the era of full scenarios, full connectivity, and full intelligence. ALSA, as an important audio architecture in Linux systems, allows developers to use Linux system calls in programs to control and manage the underlying operating system. Due to its efficient and easy-to-use features, it is also suitable for embedded devices, which aligns well with OpenHarmony's concept of supporting a variety of devices. Currently, ALSA is widely used in the mobile application development field of OpenHarmony. We will submit the adaptation code via a pull request (PR) as soon as possible. This issue is created to engage in in-depth discussions with the community about integrating the adaptation code. We sincerely welcome any valuable suggestions. ## Adaptation Plan 1. Details of the ALSA adaptation plan: 2. Submit back to the main community. 3. Ongoing community maintenance. ## Test Results We have completed large-scale compatibility testing, covering different versions of HarmonyOS and various types of HarmonyOS devices. The test results show that the modified version is highly compatible with the HarmonyOS system and no significant stability issues have been observed. Benefits to the Upstream Community * Can reach OpenHarmony’s large user base and developer community. * By supporting the development trends of the operating system, it ensures the long-term development potential of the project. * Enhances the project's processing capability in diverse operating environments.

I found that other sample rate produces very low quality, garbled audio. I read that this is because SPDIF only supports 48kHz in hardware, and any other sample rates require the Realtek drivers.
