e62b586273 Jack: Add a port-type filter expression to calls to jack_get_ports() so that only audio ports are listed (removing eg Midi etc) as reported by 'sqweek'. 2013-11-15 12:27:07 +00:00

e2662ae2ad Alsa: Revise the use of the environment variable 'PA_ALSA_PLUGHW' so it correctly influences the Device-List and the capabilities reported. Also rename a mis-leading variable and add one additional DEBUG line. 2013-10-17 12:44:09 +00:00

c23e362fcb pa_mac_core.c line 664 fixed incorrect memset size (was using sizeof(ptr) not sizeof(struct type) 2013-08-29 00:36:56 +00:00

3029485a0e Alsa: Add function to prevent duplicate parts in the visible pa device name string, that occur when the pcm-device name starts with the card name (since they are both used). Achieved by trimming the pcm-device string beginning. 2013-08-27 17:14:51 +00:00

bbf60ab137 Alsa: Fix memory leak as nonMmapBuffers were not freed (since change to realloc). Clean out corresponding dead code chunk. 2013-08-22 22:01:17 +00:00

d17353a602 Alsa: Rename some variables in pa_linux_alsa where the meaning is mis-leading or wrong in the Alsa context. Also tweak one debug message and a few typos. 2013-08-22 19:43:07 +00:00

b1a62661bf Alsa: Fix handling of poll descriptors in PaAlsaStream_WaitForFrames(). Otherwise if capture signals before playback a duplex stream could poll the wrong descriptor, causing a loop (reported by Alexander Kartashov). 2013-08-13 20:37:04 +00:00

2a992efaa8 fixed bug that was causing memory corruption in PA/ALSA when host sample format was lager than user format. e.g. using 16 bit output with a sound card that used 24 bit buffers. the incorrect input zeroer was being used. Thanks to Anders Tornvig for identifying the problem 2013-08-06 08:26:55 +00:00

80c77d9ae4 OSS: revise default latency reporting: previous fixed values could not actually be achieved with OSS power-of-2 sizes. Instead try a configuration and correctly report the default latency based on one less than the number of fragments; also fix the stream component 'bufSz' calculation. 2013-06-08 19:30:41 +00:00
gineera
28f9ee0965 Alsa: revise latency use and calculations, since the latency should be equivalent to one Alsa period less than the Alsa ringbuffer (was based on the whole). Also fixes failure if zero latency was specified. 2013-06-08 19:12:25 +00:00

a51584e3b1 factored out InitPaDeviceInfoFromAsioDriver function. skip device rather than failing entire init process if a single ASIO driver returns an error during init. This was happening with MOTU devices if the device wasn't present. See ticket #221 2013-05-02 01:06:01 +00:00

6803965617 General: 
- Change of CMake options to utilize built in header configuration support (PA_USE_*)
- Added CMakeLists.txt for examples
- Added paex_ocean_shore.c as an example how to use PA ring buffer for lock-free communication with the audio callback
WDM-KS:
- Added better default sample rate support
- Made sure that all pins now have a name, even if only "Input" or "Output"
- IsUSBDevice fixed acc. to Alex Lessard's suggestion
- IsNameUSBAudioDevice fixed similarly

d998066452 alsa: 
- support for sub-devices;
- fixed 24-bit format support for some devices which on little-endian machine operate only in big-endian format, example of such device is Audio4DJ which supports only SND_PCM_FORMAT_S24_3BE (for this patch implemented support only for 24-bit audio samples although other formats may be added in case of necessity and if such devices exist);
! special thanks to Owen Williams from Mixxx project who tested these changes/fixes on real Audio4DJ device.
