From b23975e60a944e1a3ef419a01838fca51a29baf3 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Fri, 23 Sep 2022 10:22:36 +0200 Subject: [PATCH] ALSA: hda/hdmi: Limit the maximal count of PCM devices to 8 The current hardware has up to 4 converters. Save little space. The limit 8 is enough even for a more improved hardware.
