Alexa volume not adjustable by voice command, Assistant comparatively too quiet

[rsuhendro]

Python 2 & 3 releases (python2 --version and python3 --version):

**Python 2.7.9 & Python 3.4.2**

Description of problem:

The voice output level of Google Assistant is too low. Sometimes the hotword **Google** was also missed, no triggering.

Expected:

The same level as the AlexaPi.

Steps to reproduce:

Traceback (if applicable):

Additional info:

Run on RPI 3 with Raspbian Jessie Lite. I use PulseAudio in the config.yaml because for unknown reason I can't make AlexaPi works with ALSA.
I've set the volume level using alsamixer.

Hi,

have you tried setting the output volume by using Google's and Alexa's native voice commands? For Alexa, this works (it starts with a default of ~80%). The Google SDK, which AssistantPi uses, claims to suport voice control for volume, but I haven't tested it yet.

Just fyi, AssistantPi defaults to using pulseaudio since release 1.0 and does all necessary settings during the setup.

I've tried to reduce default_volume to 40% in config.yaml but Alexa is still loud. I can't find the volume control command for Google SDK. Any hints?

Same issue with a RPI 2, has anyone been able to increase the volume for Google SDK. It is way too low if compare with Alexa.

found the voice command to increase googles voice, https://support.google.com/googlehome/answer/7072489?hl=en

Thanks. It works. I can set max volume (level 10). But somehow Alexa is still louder, so I need to find a way to lower it.

Sorry, I've been out of town for some days - you can adjust Alexa's volume with it's native voice command, simply say "Alexa, louder/softer" or "Alexa, Voume 4" https://www.amazon.com/gp/help/customer/display.html?nodeId=201619520

Just perfect...fully solved. Thanks a lot.

It seems that adjusting Alexa's volume isn't working properly (RPi Zero W). I get the message in debug mode, that volume has been adjusted, but there's no difference between 2 and 10... Anyone else experiencing this issue?

I am also facing the same issue, no matter what i try alexa i always so much louder. The volume doesnt seem to change.

I also have an issue with google activating at almost any word, even if its the tv it activates and starts talking.

Great work though.

Yes the command works: Volume 4

But the voice level is as loud as before..

tried to hack around this problem by setting the system volume via subprocess/pexpect using amixer -D pulse sset Master 50%, but it seems to have no effect on the daemon, even if it runs in the same scope (i.e. run by service, not manually by a Linux user account). Anyone any ideas on this?
