From 2eb65d67afbf9364b525b657f1475d1a2cbc27de Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Thu, 31 Dec 2015 13:58:14 +0900 Subject: ALSA: dice: expand timeout to wait for Dice notification Some users have reported that their Dice based models generate ETIMEDOUT when starting PCM playback. It means that current timeout (=100msec) is not enough for their models to transfer notifications. This commit expands the timeout up to 2 sec. As a result, in a worst case, any operations to start AMDTP streams takes 2 sec or more. Then, in userspace, snd_pcm_hw_params(), snd_pcm_prepare(), snd_pcm_recover(), snd_rawmidi_open(), snd_seq_connect_from() and snd_seq_connect_to() may take the time.
