MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
setlocale() is not thread-safe. It can actually trigger a crash if
another thread uses locale informations at the same time in the process.
Library code should use POSIX newlocale/duplocale/uselocale/freelocale
instead. Those functions only change the locale data for the calling
thread.

Subject: [PATCH 03/21] seq: Fix for snd_seq_parse_address()
snd_seq_parse_address() uses strncmp() to compare the client name
in the string argument with the existing clients, until it finds one
name matching the same leading characters. This may produce wrong
results when there are two sequencer clients with similar names.
Example: "KMidimon" : "Kmid"

Subject: [PATCH 04/21] control: tlv: Check dB range only within the control's volume range
The DB_RANGE need to be used on some HW, since the gain on
volume control is not continuous, and has to be divided into
several sub DB_SCALE ranges.
ASoC has a feature to override the HW default volume range,
and in this case when the volume range is less than the
HW maximum we do not need to go through the whole DB_RANGE,
but we need to stop where the kcontrol's maximum tell us.

Subject: [PATCH 07/21] tlv: Handle 'holes' in SND_CTL_TLVT_DB_RANGE array
When converting from dB to raw value, and DB_RANGE is
used with non overlapping map, dB value in between the
sub ranges will be not found.
For example, if the control has the following:
0: -10dB
1: -5dB
2: 0dB
3: 2dB
4: 4dB
static const unsigned int nonoverlapping_tlv[] = {
TLV_DB_RANGE_HEAD(2),
0, 2, TLV_DB_SCALE_ITEM(-1000, 500, 0),
3, 4, TLV_DB_SCALE_ITEM(200, 200, 0),
};
Range 1: -10 .. 0dB
Range 2: 2 .. 4dB
If user asks for 1dB the snd_tlv_convert_from_dB will not find
the raw value, since the 1dB is not part of either range.
To fix this, we will store the previous non maching range's
maximum raw value. If the dB value is not found in the next range,
we will check, if the requested dB value is in between the current
and the previous range, and if it is than pick the apropriate raw
value based on the xdir (up or down rounding).

Subject: [PATCH 14/21] pcm: add defaults.pcm.minperiodtime parsing
Some broken applications like Audacious don't set any timing parameters.
While the alsa-lib behaviour is to select the smallest period size and
biggest buffer size, the result is the generation of thousands
interrupts per second.
The default value in alsa.conf is 5000usec.

Subject: [PATCH 15/21] pcm: introduce defaults.pcm.compat to change the params choose behaviour
Having getenv directly in the function is not a good idea. Allow
configuration of the behaviour change in snd_pcm_param_choose() function
using alsa.conf. Use the environment variable LIBASOUND_COMPAT only
as fallback.

From 91c9c8f1b85e69b4bdc94a777d2767c4906c3f47 Mon Sep 17 00:00:00 2001
From: Jaroslav Kysela <perex@perex.cz>
Date: Mon, 23 Aug 2010 17:05:36 +0200
Subject: [PATCH 20/21] general: recoded snd_dlobj_ functions
- changed logic to get/put blocks
- added mutex locking of the symbol list
- added reference counting (do not free used dl handles)
