sound: fix drivers needing module.h not moduleparam.h

2011-10-31T23:31:19+00:00

The implicit presence of module.h lured several users into
incorrectly thinking that they only needed/used modparam.h
but once we clean up the module.h presence, these will show
up as build failures, so fix 'em now.

sound: rawmidi: disable active-sensing-on-close by default

2009-07-15T09:57:20+00:00

Sending an Active Sensing message when closing a port can interfere with
the following data if the port is reopened and a note-on is sent before
the device's timeout has elapsed.  Therefore, it is better to disable
this setting by default.

sound: seq_midi: do not send MIDI reset when closing

2009-07-15T09:56:58+00:00

Sending a MIDI reset message when closing a port is wrong because we
only want to shut the device up, not to reset all settings.
Furthermore, many devices ignore this message.

Fortunately, the RawMIDI layer already shuts the device up, so we can
ignore this matter here.

seq-midi: always log message on output overrun

2009-07-15T09:56:06+00:00

It turns out that the main cause of output buffer overruns is not slow
drivers but applications that generate too many messages.  Therefore, it
makes more sense to make that error message always visible, and to
rate-limit it.

[ALSA] Remove sound/driver.h

2008-01-31T16:29:48+00:00

This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

[ALSA] rawmidi: add get_port_info callback for sequencer information flags

2006-06-22T19:33:20+00:00

Add a get_port_info callback to the snd_rawmidi_global_ops structure to
allow the USB MIDI driver to supply information flags for the sequencer
ports created by seq_midi.

[ALSA] add more sequencer port type information bits

2006-06-22T19:33:18+00:00

Add four new information flags SNDRV_SEQ_PORT_TYPE_HARDWARE, _SOFTWARE,
_SYNTHESIZER, _PORT for sequencer ports.  This makes it easier for apps
like Rosegarden to make policy decisions based on the port type.

[ALSA] Change seq_midi.c so client name is card, rather than port, specific

2006-06-22T19:32:46+00:00

Change snd_seq_midisynth_register_port() in seq_midi.c so that if a new client
is created, the client name string is based on card->shortname not
(port-specific) info->name.
