Re: [pulseaudio-discuss] [PATCH 00/10] Enable building for win32
'Twas brillig, and Maarten Bosmans at 06/01/11 01:39 did gyre and gimble: This patch series makes Pulseaudio compile for Windows using mingw. Moverover, pacat and pactl actually work on Windows. A running daemon is something to do another time. (Pierre, are you still interested in this?) It should be farily noncontroversial, as most changes should not affect operation on Linux. Wow, awesome work! I'll review and apply/comment shortly. Many thanks.

I'm not sure this is correct. pa_get_temp_dir() might return $HOME/tmp
(it does here) so this path is not correct (it is the old legacy runtime
dir after all). There was some talk to disable this anyway so it may be
worth just dropping the code (there is a configure switch for it
already IIRC). That can be in another patch tho' (after discussion), so
possibly just remove this hunk for now.

It would make sense to make these two separate asserts so we know which

Both volumes are in alsamixer. Is there any way to fix this in Pulseaudio (some kind of quirks database, for example)? This isn't an uncommon thing, but it's getting better. The problem is very likely that the device is incorrectly reporting it's dB range and thus PA cannot control it correctly. It's possible to add quirks in the driver to correct the range. http://www.pulseaudio.org/wiki/BadDecibel http://mailman.alsa-project.org/pipermail/alsa-devel/2010-February/025213.html David Henningsson from Canonical also wrote a similar tool: http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/7542 I'm not sure off hand what the latest version of that tool is or if there is a proper webpage for it. David, can you elaborate? No, there isn't one. Here's the latest version: https://launchpad.net/~diwic/+archive/maverick (for Ubuntu 10.10) https://launchpad.net/~diwic/+archive/ppa (for Ubuntu 10.04) https://launchpad.net/~diwic/+archive/ppa/+files/alsamixertest_48.11.tar.gz (for other distros) It currently tests playback only. Before it makes sense to test recording as well, we'll have to fix up the input mixer paths in PulseAudio. I'm currently working on that, and making good progress. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

Subject: [PATCH] Implement Fortemedia SMA processing.
Those small array microphones returns two channels of opposite
phase thus the default remap in pulseaudio doing the sum output
silence.
Sounds very useful, but...
+void pa_fmaudiosma_run(pa_fmaudiosma *fs, const uint8_t *rec, uint8_t *out,
int n) {
+unsigned i;
+
+float *d, *s;
+int n_frames = n / (sizeof(float) * 2);
+memset(out, 0, n_frames * sizeof (float) * 2);
+
+d = (float *)out;
+s = (float *)rec;
+for (i = n_frames; i 0; i--, s += 2, d += 2)
+ d[0] = d[1] = s[0] - (s[0] + s[1]);
s[0] - (s[0] + s[1]) can be simplified to -s[1], unless my junior
high math fails me completely. Are you sure you don't mean s[0] - s[1]?
