Subject: [PATCH v2] ALSA: usb-audio: Add quirk for PreSonus AudioBox USB
Date: Tue, 28 Apr 2026 06:21:19 +0530 [thread overview]
Message-ID: <20260428005433.6326-1-abhi220204@gmail.com> (raw)
In-Reply-To: <20260410143335.5974-1-abhi220204@gmail.com>
The PreSonus AudioBox USB (0x194f:0x0301) only supports S24_3LE
format for both playback and capture. It does not support S16_LE
despite being a USB full-speed device. Add explicit format quirks
for both the playback (interface 2) and capture (interface 3)
interfaces to ensure correct format negotiation.

v2: Fix placement - entry was incorrectly inside a #if 0 disabled block.
Moved to after the #endif /* disabled */.
