Subject: [PATCH] usb/caiaq: decrease period_bytes_min
Date: Thu, 24 Jan 2008 18:44:07 +0100 [thread overview]
Message-ID: <20080124174407.GA12888@buzzloop.caiaq.de> (raw)
[-- Attachment #1: Type: text/plain, Size: 299 bytes --]
This patch increases the snd_pcm_hardware->period_bytes_min field in the
caiaq/usb audio driver. The hardware can actually handle as few as 128
bytes, depending on the system. So it makes no sense to keep
applications from actually using such values.
