Author: Mike Brady <mikebrady@eircom.net>
Replace the code for determining when resends should be sent for missing audio packets.

Multiple sequential resend requests are now rolled up into one.

Should address Issue #865.
 2019-09-22 21:04:07 +01:00
Mike Brady e8a92d3c3b ensure alsa mixer is initialised before trying to set volume. Normalise the 'pvol' volume mesasages to the hardware devices' maximum volume when using combined hardware and software attenuation. 2019-09-10 13:03:54 +01:00
Mike Brady b59dd4229e fix regression no volume metadata was being sent if configured to ignore volume control -- issue #903. 2019-09-10 09:56:25 +01:00

Chris Boot b9cf91b2bb More typo fixes across the tree 
Previously I have made spelling changes as caught by Debian's lintian
tool, which has a short list of common misspellings that it tests for.
This time I decided to run codespell against the source and fix all the
obvious problems it came up with. It also uses a list of misspellings
but it's much larger than lintian's, but also has some false positives
so I went over the list by hand.

The command I used to do check the source was:
git ls-tree -rz --name-only HEAD | xargs -0 codespell -L minimise,errorstring

Mike Brady 83c0405d03 Add automatic bit depth and speed selection for alsa devices. Set rate and format to "auto" by default. Always look for the greatest bit depth, but the lowest multiple of 44,100. 
Improve support for big-endian CPUs by adding support for explicit -endian formats, i.e. S16_LE, S16_BE, S24_LE, S24_BE, S32_LE, S32_BE.

For the "disable_standby_mode" setting, change "while_active" to "auto".

Mike Brady 1d32976d07 Improve support for bigendian devices. Add support for S16_LE, S16_BE, S24_LE, S24_BE, S32_LE and S32_BE formats. Make the default S16_LE. Allow precision timing only on alsa devices with names beginning with "hw:". Use snd_pcm_hw_params_is_monotonic() to see if clock is monotonic. 2019-05-01 11:01:15 +01:00

Mike Brady 042d940415 Remove the AUTO bit-depth setting. It's a hack and needs more consideration. 2019-02-28 14:21:05 +00:00
Mike Brady 20967812ad Fix a bug in the activity_monitor software that could lock up a player thread so that it couln't be cancelled. If a player was cancelled while performing an activity script, the activity_monitor_mutex would remain locked. 2019-02-26 15:23:11 +00:00
