[PATCH v4] ALSA: virtio: use ack callback
by Matias Ezequiel Vara Larsen 31 Oct '23

31 Oct '23

This commit uses the ack() callback to determine when a buffer has been updated, then exposes it to guest. The current mechanism splits a dma buffer into descriptors that are exposed to the device. This dma buffer is shared with the user application. When the device consumes a buffer, the driver moves the request from the used ring to available ring. The driver exposes the buffer to the device without knowing if the content has been updated from the user. The section 2.8.21.1 of the virtio spec states that: "The device MAY access the descriptor chains the driver created and the memory they refer to immediately". If the device picks up buffers from the available ring just after it is notified, it happens that the content may be old. When the ack() callback is invoked, the driver exposes only the buffers that have already been updated, i.e., enqueued in the available ring. Thus, the device always picks up a buffer that is updated. For capturing, the driver starts by exposing all the available buffers to device. After device updates the content of a buffer, it enqueues it in the used ring. It is only after the ack() for capturing is issued that the driver re-enqueues the buffer in the available ring.

[PATCH alsa-ucm-conf 1/2] bytcr-wm5102: Add support for speakers connected to HPOUT2
by Hans de Goede 31 Oct '23

31 Oct '23

On the Lenovo Yoga Tab 3 YT3-X90 the speaker amplifiers are connected to the HPOUT2 output pins instead of the the SPK output pins. Check for "cfg-spk:hpout2" in the components string which indicates this setup and add a ucm2/codecs/wm5102/HPOut2-Speaker.conf file for this setup.

[PATCH alsa-ucm-conf] chtnau8824: Mono speaker fixes
by Hans de Goede 31 Oct '23

31 Oct '23

2 mono speaker setup fixes: 1. Use the kernel's components string to check for a mono-speaker device when the board has a components string. 2. So far known nau8824 boards with a mono speaker where using the right speaker channel, which is unusual. Normally mono speaker setups use only the left speaker channel. The Cyberbook T116 tablet is a nau8824 based model, which indeed uses the left speaker channel for its single speaker. Modify ucm2/codecs/nau8824/MonoSpeaker.conf to send a left+right channel mix to both speaker channels, so that things will work independent of which speaker channel is used for a mono setup.
