From ca1f30ad6c3f002d1d9b9355a53b8bbf2fe70588 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Tue, 13 May 2008 09:26:01 +0200 Subject: [ALSA] virtuoso: restrict period time to less than 10 s Add a constraint for the period time so that there are less than ten seconds between interrupts so that ALSA does not assume that the device is dead.
