From: emikkva Date: Mon, 16 Feb 2015 21:43:06 +0000 (+0200) Subject: Add a card attribute for alsa and alsabar X-Git-Url: https://git.madduck.net/etc/awesome.git/commitdiff_plain/5a1a02a63dc9e203f1df9a39ca657fd62677a258?ds=sidebyside;hp=-c Add a card attribute for alsa and alsabar Currently alsa.lua and alsabar.lua do not support the amixer command line option "-c" which allows defining which card to use. For at least new Dell E-series laptops, the card is not the default (0) and therefore this functionality is required for these widgets to work. --- 5a1a02a63dc9e203f1df9a39ca657fd62677a258 diff --git a/widgets/alsa.lua b/widgets/alsa.lua index f62a150..5a4335e 100644 --- a/widgets/alsa.lua +++ b/widgets/alsa.lua @@ -12,7 +12,8 @@ local newtimer = require("lain.helpers").newtimer local wibox = require("wibox") local io = { popen = io.popen } -local string = { match = string.match } +local string = { match = string.match, + format = string.format } local setmetatable = setmetatable @@ -22,6 +23,7 @@ local alsa = {} local function worker(args) local args = args or {} + local card = args.card or "0" local timeout = args.timeout or 5 local channel = args.channel or "Master" local settings = args.settings or function() end @@ -29,7 +31,7 @@ local function worker(args) alsa.widget = wibox.widget.textbox('') function alsa.update() - local f = assert(io.popen('amixer -M get ' .. channel)) + local f = assert(io.popen(string.format("amixer -c %s -M get %s", card, channel))) local mixer = f:read("*a") f:close() diff --git a/widgets/alsabar.lua b/widgets/alsabar.lua index 65a2b33..fa10bc2 100644 --- a/widgets/alsabar.lua +++ b/widgets/alsabar.lua @@ -25,6 +25,7 @@ local setmetatable = setmetatable -- ALSA volume bar -- lain.widgets.alsabar local alsabar = { + card = "0", channel = "Master", step = "5%", @@ -97,6 +98,7 @@ local function worker(args) local ticks_size = args.ticks_size or 7 local vertical = args.vertical or false + alsabar.card = args.card or alsabar.card alsabar.channel = args.channel or alsabar.channel alsabar.step = args.step or alsabar.step alsabar.colors = args.colors or alsabar.colors @@ -115,7 +117,7 @@ local function worker(args) function alsabar.update() -- Get mixer control contents - local f = io.popen("amixer -M get " .. alsabar.channel) + local f = assert(io.popen(string.format("amixer -c %s -M get %s", alsabar.card, alsabar.channel))) local mixer = f:read("*a") f:close() @@ -129,7 +131,6 @@ local function worker(args) alsabar._current_level = tonumber(volu) alsabar.bar:set_value(alsabar._current_level / 100) - if not mute and tonumber(volu) == 0 or mute == "off" then alsabar._muted = true @@ -154,15 +155,15 @@ local function worker(args) awful.util.spawn(alsabar.mixer) end), awful.button ({}, 3, function() - awful.util.spawn(string.format("amixer set %s toggle", alsabar.channel)) + awful.util.spawn(string.format("amixer -c %s set %s toggle", alsabar.card, alsabar.channel)) alsabar.update() end), awful.button ({}, 4, function() - awful.util.spawn(string.format("amixer set %s %s+", alsabar.channel, alsabar.step)) + awful.util.spawn(string.format("amixer -c %s set %s %s+", alsabar.card, alsabar.channel, alsabar.step)) alsabar.update() end), awful.button ({}, 5, function() - awful.util.spawn(string.format("amixer set %s %s-", alsabar.channel, alsabar.step)) + awful.util.spawn(string.format("amixer -c %s set %s %s-", alsabar.card, alsabar.channel, alsabar.step)) alsabar.update() end) ))
