A larger buffer (e.g. 2048) is preferred for systems using PulseAudio. The default 64 is chosen just for compatibility reasons. - On x86 systems, the default is 2048 as a reasonable value for - most of modern systems. + On x86 systems, the default is zero as we need no preallocation. Note that the pre-allocation size can be changed dynamically via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too. diff --git a/sound/hda/hdac_stream.c b/sound/hda/hdac_stream.c index a6ed3dc35f7e..1eb8563db2df 100644 --- a/sound/hda/hdac_stream.c +++ b/sound/hda/hdac_stream.c @@ -618,7 +618,7 @@ void snd_hdac_stream_sync_trigger(struct hdac_stream *azx_dev, bool set, EXPORT_SYMBOL_GPL(snd_hdac_stream_sync_trigger); /** - * snd_hdac_stream_sync - sync with start/strop trigger operation + * snd_hdac_stream_sync - sync with start/stop trigger operation * @azx_dev: HD-audio core stream (master stream) * @start: true = start, false = stop * @streams: bit flags of streams to sync |
