Subject: [PATCH v2 12/17] ALSA: emu10k1: fix wavetable offset recalculation
Date: Thu,  4 Apr 2024 12:00:43 +0200	[thread overview]
Message-ID: <20240404100048.819674-13-oswald.buddenhagen@gmx.de> (raw)
In-Reply-To: <20240404100048.819674-1-oswald.buddenhagen@gmx.de>

The offsets are counted in samples, not in bytes.

While the code block is being rewritten, also move it up a bit, to avoid
churn in a subsequent patch.
