+# This file contains error suppression rules for Valgrind. These rules suppress
+# errors in alsa-lib that are caused by Valgrind not handling the
+# SNDRV_CTL_IOCTL_TLV_READ ioctl. More information about the Valgrind bug:
+# http://thread.gmane.org/gmane.comp.debugging.valgrind/11888
+#
+# To use this file, pass the command line option --suppressions=<filename> to
+# Valgrind.
+#
+# If you find new false positives, and want to add new suppressions, the
+# --gen-suppression=all option can be very useful. It prints automatically
+# generated suppression rules that can be copy-pasted here.
