24 int "Pre-allocated buffer size for HD-audio driver"
28 Specifies the default pre-allocated buffer-size in kB for the
29 HD-audio driver. A larger buffer (e.g. 2048) is preferred
30 for systems using PulseAudio. The default 64 is chosen just
31 for compatibility reasons.
33 Note that the pre-allocation size can be changed dynamically
34 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.
38 # this config should be selected only for Intel ACPI platforms.
39 # A fallback is provided so that the code compiles in all cases.
