SND_MAESTRO3(4)

🦋 snd_maestro3(4) 🦋

okay bestie, welcome to the snd_maestro3(4) page from the Kernel Interfaces Manual — it’s literally all about the ESS Maestro3/Allegro-1 bridge device driver, and we’re gonna get into it 💅

---

💖 NAME 💖

snd_maestro3 — the ESS Maestro3/Allegro-1 bridge device driver. That’s the whole name-vibe, periodt ✨

---

🎀 SYNOPSIS 🎀

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device sound
device snd_maestro3

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

snd_maestro3_load="YES"

slay, that’s the whole setup 🫶

---

🌸 DESCRIPTION 🌸

The snd_maestro3 driver provides support for the ESS Maestro3 and Allegro-1 sound chips under the PCM framework. These chips are mostly found in laptop computers and feature an AC97 mixer, a multi-channel sample rate converter that can mix up to four digital audio streams in hardware, recording support, and external volume control buttons. it’s giving “tiny laptop sound chip with main character energy” honestly 😭🔥

The firmware for the sound processor is licensed under the GNU Public License, and thus this driver is not included in the default GENERIC kernel. no cap, that’s important — don’t go looking for it in GENERIC and then act surprised 🙈

🌈 HARDWARE 🌈

The snd_maestro3 driver supports the following audio devices:

• ESS Technology Allegro-1
• ESS Technology Maestro3

those are the two supported icons, bestie 👑

---

🎀 DIAGNOSTICS 🎀

The hardware volume control buttons can be connected to two different pin sets (GPIO or GD) on the chip, depending on the manufacturer. The driver has no way of determining this configuration, so a hint may be used to override the default guess. The default setting for hardware volume control assumes that GD pins are wired to control the hardware volume.

For systems that have the GPIO pins wired to the hardware volume control buttons, add the line

hint.pcm.0.hwvol_config="0"

to the file /boot/device.hints to override the default setting.

lowkey important: if your volume buttons are being weird, this hint is the vibe check you need 💀✨
