Google didn't show any hits for this issue with respect to SCID in
particular so I thought I'd report it. SCID relies on snack for
announcing moves. Snack has been maintained to varying degrees on
different distributions, there is a catch {} around the actual move
announcement call so it was silently failing for me on ubuntu.
Apparently snack now needs to be compiled with ALSA support enabled
(which Ubuntu doesn't do) or it will complain about the absence of
/dev/sound/dsp. To add insult to injury snack's alsa code relies on a
private symbol in the PCM library which is no longer exported and thus
now requires the patch below which I found here:
http://forum.myah.org/viewtopic.php?p=7274&sid=3fd8e925b927c1ee06dabcdbf9a6238eThe "speak" script from crafty was initially a quick workaround but it doesn't make blocking calls to esdplay so sounds aren't always clear. I tried out the move announcement feature in SCID today because I like to walk through master's games on a physical board and I find it distracting to move my eyes back and forth from the board to a sheet with the list of moves. Grandmasters frequently resign many moves before checkmate and it is a bit unsettling to simply have it stop announcing moves so after having familiarized myself with SCID a little bit to diagnose the aforementioned problem I added a "black resigns", "white resigns", "draw" feature. I didn't add the localization field for quite every language because I wasn't convinced that a patch would be accepted. The patch for this can be found here: http://pastebin.com/GTLFby3c One will obviously need additional .wav files - I just recorded it myself. Keep up the good work.
