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

I've been away this weekend but tested your solution this morning and it works excellent (although the refresh_ao command produces a lot of errors). Hardware volume control works fine now, Thanks.

Customisation of the max level (or perhaps different curves for different popular DACs) would be a great blessing: I have the IQaudio DAC, and 96% volume corresponds to 0dB. So if you put the volume to 100% and play a track that has been normalised, it clips.... It would be nice if, when you do the volume curve mapping for this DAC, setting 100% on the RuneUI actually sent 96% to the hardware.

Yes, I would also vote for a remapping of the range to better fit with what the actual values from alsamixer are doing. (Using IQAudIO DAC+)
I realize this is a bit off thread topic, but there seems to be a discussion here already so I thought I would throw in my vote too.

Second that thought (IQaudio Pi-dac)

No joy so far.

Step 1. I login in with user: root and password:

After executing your step 2: I see : " (integer) 0"

After executing step 3: I see: " Locked!"

And I can't go to step 4 since I have to use the ip address.

But when I go to ip addres http://192.168.178.27/mpd/ I cannot choose the hifiberry dac+

Kind regards,
Bas

A little off topic but alsa has calls that allow the application to get the range / max and min values from the sound card's driver.

In the IQaudIO Pi-DAC(s) I've set 100% to +4db, and 0% to -103.5db (mute on the TI PCM5122 DAC) I did this as the PCM5122 will actually allow you to go up to +23db or thereabouts and if you want clipping then that was what you achieved

Anyway, just FYI

Hi ACX,
with control volume in place with Hifiberry dac+ the sound of HiRes (24b 192kHz) has clicks and pause.
When I flash the SD Card, without volume control,It is very good !
