VOLUME CONTROL ISSUES - Volumio1.55 - RPi Zero - DAC pHAT

Hi,

how to make software volume control in Raspberry Pi Zero DAC pHAT http://learn.pimoroni.com/tutorial/phat/raspberry-pi-phat-dac-install

I nice Dac for Zero, but a little difficult and tedious to put Volumio on it.
I have done all the steps of this forum:
https://volumio.org/forum/volumio-rpi-zero-t3797.html
And after about six hours of work in Raspi A+ (update, upgrade ,dist-upgrade,…,install binutils and rpi-update), and put this SD on the Zero (with phat Dac), it boots perfectly.
Now in Zero, i did the installation:
learn.pimoroni.com/tutorial/phat … ac-install
And Zero runs volumio 1.55 with Jessie.
I have let a copy of this image sd in my drive:
https://drive.google.com/open?id=0BxkNJU-R-TAlM2JrZlRGa2ZRZzA

You need only to put this image on a SD (2Gigas minimun) with dd command,boot Zero with this SD, setup a wifi Access Point with ssidname “volumio” and no password, for example with the your mobile, then go to with the mobile navigator (ie Opera) to 192.43.2.44:80 (change the IP for your raspi IP), and you have Volumio local web is on your navigator.
Now you can change the network config Volumio, to your home wifi, and finish.

Thanks a bunch man!! Got my volume control working - Seems like it may be a bug. I referenced your fix in this topic:
https://volumio.org/forum/rc2-volume-options-mixer-available-t4318.html#p20194

Got my Pi2 and Phat DAC working awesome!

anyone solves the volume control issue on 2.041 (it worked for me on the first 2. versions but not it stopped) Volume Control only runs on “None” if I change to “Software” there is no sound/playback

I got it working in 2.041 albeit using different hardware by the following:

In /volumio/app/volumecontrol.js below the var amixer { … }; block, add the following so we can call mpc:

[code] var mpc = function (args, cb) {

            var ret = '';
            var err = null;
            var p = spawn('mpc', args);

            p.stdout.on('data', function (data) {
                    ret += data;
            });

            p.stderr.on('data', function (data) {
                    err = new Error('MPC Mixer Error: ' + data);
            });

            p.on('close', function () {
                    cb(err, ret.trim());
            });

    };

[/code]
Then also change the self.setVolume { … }; block to use mpc instead of amixer by changing to this:

self.setVolume = function (val, cb) { // if (volumecurve === 'logarithmic') { // amixer(['-M', 'set', '-c', device, mixer, val + '%'], function (err) { // cb(err); // }); // if (devicename == 'PianoDACPlus' || devicename == 'Allo Piano 2.1') { // amixer(['-M', 'set', '-c', device, 'Subwoofer Digital', val + '%'], function (err) { // cb(err); // }); // } // } else { // amixer(['set', '-c', device, mixer, val + '%'], function (err) { // cb(err); // }); // if (devicename == 'PianoDACPlus' || devicename == 'Allo Piano 2.1') { // amixer(['set', '-c', device, 'Subwoofer Digital', val + '%'], function (err) { // cb(err); // }); // } // } mpc(['volume', val], function (err) { cb(err); }); };
Then add the ‘mixer_type’ line to /etc/mpd.conf below the audio_output section so it looks like this:

# Audio Output ################################################################ audio_output { ... ... } mixer_type "software"

Thx, I’ll give it a try later today

Hi,

I’ve got volume problems too.

I’m running Volumio 2, with a raspberry pi zero and phat dac. It plays music and so on, but I cannot control the volume. Do any of you have any advise?

Have you or sombody a solution for the problem? for v2.201
