[BugFix] HiFiBerry DAC+ HW Volume (RuneAudio 0.3-beta)

[Tom2112]

This is a known issue, but nothing we can solve at the moment.

So what would you recommend? Just use software volume control?

Does this affect all DACs? I'm experiencing it on my SainSmart SX400 (which pretends to be an IQaudIO DAC+).

Thanks for this, I got it to work this time.
I also find that the volume control is really only usable between 60 and 100, can we fix this or is it a hardware issue?

I have just released a hack for this. There is an executable for Pi model 1 which you can try.

Hmmm. When I run the "redis-cli.....", I get- "(interger) 0" displayed. Is that a good thing or a bad thing?
Then when I run the "refresh_ao" I get "command not found".
My guess is the refresh_ao error is a path related issue? Which folder does this command reside?

I'm using a HiFiBerry Dac+. It's working except the hardware volume control fails to work. Software enabled works, but it effects the sound quality. I'm hoping if I can get your command to work, it'll fix this.

Hello,

I've tried all the suggestions here, and I can't get HW volume control to work with HifiBerry Dac+ Pro and Pi2, I think its related to the fact that I can't get the audio_output mpd.config, as shown below from the guide to match the same syntax.

Any ideas?

#expected output
audio_output {
name "snd_rpi_hifiberry_dacplus"
type "alsa"
device "hw:1,0"
mixer_control "Master"
mixer_type "hardware"
mixer_device "hw:1"
auto_resample "no"
auto_format "no"
enabled "yes"

#my output
audio_output {
name "snd_rpi_hifiberry_dacplus"
type "alsa"
device "hw:1,0"
mixer_control "Digital"
mixer_type "hardware"
mixer_device "hw:1"
auto_resample "no"
auto_format "no"
enabled "yes"
}

Hi drfrink24,

…I can't get HW volume control to work with HifiBerry Dac+ Pro…

I have the same DAC, no problems, it really does work. See this post for a possible solution: post26802.html This problem has been fixed in the latest version of 0.5b.
