0 Going through the threads I see many unresolved issues with HDMI sound. Tried many of the suggested fixes. My HDMI TV display is working fine: with xrandr I get this: HDMI-1-1 connected primary **xrandr --output HDMI-1-1 --set audio on** warning: output HDMI-1-1 not found; ignoring X Error of failed request: BadRROutput (invalid Output parameter) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 15 (RRGetOutputProperty) Serial number of failed request: 45 Current serial number in output stream: 45 sound multiple-monitors hdmi share | improve this question edited Jan 18 at 17:34

1 $begingroup$ I have a list: lis = {{"abc", 1, 2}, {"cde", 3, 4}, {"fgbc", 5, 6}} I would like to select list items that have first elements that end in the string "bc" to give: res = {{1,2},{5,6}} This is a variant on this question which has to do with strings only. Thank you as always for suggestions. list-manipulation string-manipulation share | improve this question asked 3 hours ago Suite401 Suite401 988 3 12 $endgroup$
