MAESTRO(4) — Kernel Interfaces Manual 🎧💖

okay so bestie, this page is from the Kernel Interfaces Manual, and it's the whole tea on maestro — the ESS Maestro 1 and 2 audio device. Pull up a chair, we're getting into it. ✨

🌸 NAME 🌸

maestro — ESS Maestro 1 and 2 audio device. That's the short version, and yes she's an icon. 💅

🦋 SYNOPSIS 🦋

maestro* at pci?
audio* at maestro?

💖 DESCRIPTION 💖

The maestro driver supports ESS maestro 1, 2 and 2E, including OEM products that identify as NEC Versa, or NEC VersaProNX VA26D, as long as they use an AC'97 compliant codec. And lowkey that's always the case, except for very early models. 🫶

It does not support maestro 3 cards — those are entirely different and are supported by the esa(4) driver. Not her lane, not her problem. 💅

Maestro cards have direct support for 16 bit signed little-endian mono and stereo, 8 bit signed and unsigned mono and stereo. Other encodings are emulated in software. Sampling range is 4000 - 48000 Hz, with roughly a 2 Hz resolution. Slay. 🎶

Maestro cards have some DSP and Dolby Digital 5.1 hardware, but this driver does not support it. So don't expect that from her. 🙈

Other functions of maestro cards (modem, joystick) are not supported. Nope, not those either. 💀

PCI interrupt sharing works, as long as other devices comply too. Teamwork, bestie. 🤝

👑 SEE ALSO 👑

🌈 HISTORY 🌈

Maestro hardware information was gleaned from the FreeBSD and Linux OSS drivers. So that's where the lore came from. 📚

🎀 AUTHORS 🎀

David Leonard and Marc Espie. Shoutout to the icons who wrote this. 🫶

⭐ BUGS ⭐

Very old cards with a PT101 mixer component should have partial support, e.g., the mixer does not work. So like, partial support, but the mixer is a no-go. 😭

Recording should work soon. We're manifesting it. ✨
