In practice the speaker and the headphone are conflicting devices, see https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/Intel/sof-es… There is no such situation, and the system doesn't produce sound from speaker when headphones are plugged in. The user may manually open speaker using amixer sset 'Speaker' on or pavucontrol. The GPIO thing on Huawei Intel platform is too complicated, they use two GPIOs for headphone and speaker, and the headphone GPIO is inverted, which means low means on and high means off. Luckily there should be only one hardware config for the AMD acp3x platform GPIO and you may just choose the correct one.

[PATCH v2] ASoC: SOF: ipc4-control: Return on error in sof_ipc4_widget_kcontrol_setup()
by Peter Ujfalusi 23 Mar '23

23 Mar '23

The patch adding the bytes control support moved the error check outside of the list_for_each_entry() which was not correct as at the end of the list_for_each_entry() the scontrol will no longer point where the error happened, but it to the list head. Restore the original logic and return on the first error with the error code.

[PATCH 0/3] ASoC: SOF: ipc4/intel: Support for ChainDMA
by Peter Ujfalusi 23 Mar '23

23 Mar '23

Hi, On a platform when the DSP is in use, we cannot select individual links to use or not use the DSP, it is either all or none. On some audio endpoint, like HDMI/DP, it is preferred to not use any processing in DSP to reduce the latency and to allow bytestream pass-through (DTS, DD, etc) IPC4 introduces a new type of end-to-end connection within the DSP which is using the host DMA and link DMA in a single buffer, working back-to-back, passing the received data without looking at it or trying to understand the format, content. This mode reduces the latency and allows non PCM streams to be sent from userspace. The feature is enabled per PCM bases, signalled in topology. Regards, Peter --- Jyri Sarha (2): ASoC: SOF: ipc4: Add macros for chain-dma message bits ASoC: SOF: ipc4/intel: Add support for chained DMA Ranjani Sridharan (1): ASoC: SOF: topology: Set pipeline widget before updating IPC structures include/sound/sof/ipc4/header.h | 29 +++++++ include/uapi/sound/sof/tokens.h | 1 + sound/soc/sof/intel/hda-dai-ops.c | 18 ++++- sound/soc/sof/ipc4-pcm.c | 122 +++++++++++++++++++++++++++++- sound/soc/sof/ipc4-topology.c | 120 ++++++++++++++++++++++++++++- sound/soc/sof/ipc4-topology.h | 2 + sound/soc/sof/topology.c | 48 ++++++------ 7 files changed, 308 insertions(+), 32 deletions(-) -- 2.40.0

[PATCH] ALSA: usb-audio: Fix recursive locking at XRUN during syncing
by Takashi Iwai 23 Mar '23

23 Mar '23

The recent support of low latency playback in USB-audio driver made the snd_usb_queue_pending_output_urbs() function to be called via PCM ack ops. In the new code path, the function is performed alread in the PCM stream lock. The problem is that, when an XRUN is detected, the function calls snd_pcm_xrun() to notify, but snd_pcm_xrun() is supposed to be called only outside the stream lock. As a result, it leads to a deadlock of PCM stream locking. For avoiding such a recursive locking, this patch adds an additional check to the code paths in PCM core that call the ack callback; now it checks the error code from the callback, and if it's -EPIPE, the XRUN is handled in the PCM core side gracefully. Along with it, the USB-audio driver code is changed to follow that, i.e. -EPIPE is returned instead of the explicit snd_pcm_xrun() call when the function is performed already in the stream lock.
