From ab656a52da187dd09b4e400ca1fd13ab2f59e345 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sun, 8 Mar 2009 04:11:30 +0100 Subject: alsa: determine buffer_time if not already known This patch fixes a theoretical (but practically impossible) flaw: the variable "buffer_time" may be uninitialized when it is used. Initialize the variable with snd_pcm_hw_params_get_buffer_time(). --- src/output/alsa_plugin.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/output/alsa_plugin.c b/src/output/alsa_plugin.c index 489d4f32b..923d70ad8 100644 --- a/src/output/alsa_plugin.c +++ b/src/output/alsa_plugin.c @@ -309,6 +309,11 @@ configure_hw: &buffer_time, NULL); if (err < 0) goto error; + } else { + err = snd_pcm_hw_params_get_buffer_time(hwparams, &buffer_time, + NULL); + if (err < 0) + buffer_time = 0; } if (period_time_ro == 0 && buffer_time >= 10000) { -- cgit v1.2.3
