I wanted to report back on some issues I was having with my system (RPi B, USBDAC Schitt Modi2). Some radio stations refused to load and play, these seemed to be the higher resolution streams like Audiophile. I was using a 2.5 amp Switching PS that I had laying around.
I just received an IFI 5v iPower PS and installed it. Wow, what a difference in sound AND I now can stream the problematical radio stations. I now wonder how many weird problems people are having might be due to crappy power supplies especially with USB DACs. Just thought I'd offer it up. Anyway, great software Tim. I continue to be amazed at your effort.

Power supply issues come up again and again with RPis, including in this group.

Thanks for sharing your experience with the IFI iPOWER PS. I was reluctant to shell out the bucks for it without knowing someone had actually seen a difference using it in a setup like mine.

Looks like my usual sources in the USA all list it as a pre-order item with availability dates ranging from the middle to the end of next month.

edit: just found it in stock at Music Direct.

Hi,

I'm able to repro and can see where the logic is not designed to handle switching between I2S and USB connected at same time.

Whats the general usage scenario for this?

my scenario is pretty simple. i use the USB out to audio-gd dac/headamp to speakers the majority of the time... but i can also just grab my pi (in it's case w/ thumbdrive) and take it to work and plug my headphones into the i2s dac.

"I have a dream" to control my valve amps physical volume knob from within Moode Audio. I've found several tutorials on building a servo controller suitable for this purpose.
My question is, how can I get moode to do this? I'm hopefull that I could create a small program within raspbian as the control logic which reads from Moode some how.

Point me in the right direction please.

Hi,

An alternative might be to use a rotary encoder (volume control) and Moode as the master volume.

The method for calibrating overall volume when there are two volume controls, a master control for the DAC/Player and a second volume control downstream from the DAC, which in your case is the volume control on your valve Amp, is as follows:

1) set Amp volume to 0 (no volume)
2) set Moode volume to 100 (0dB full volume)
3) play tracks that represent the type of music you most frequently listen to
4) set Amp volume so sound is the loudest you ever want to listen at

You can leave the downstream Amp volume set at that level and then control volume exclusive from Moode. The calibration ensures that there will be no audible degradation from using the upstream (Moode) digital volume control.

thanks, tim. your effort and help is much appreciated.

if you ever need anyone to do a little c/c++ work for you, just let me know 🙂

Hi,

I just happen to have a really nice feature enhancement on my TODO list that requires coding in c. I'd do it myself but for lack of time so if you would like to take a look at the project, email tim at moodeaudio dot org and I'll fill u in 🙂

Are you guys talking about the $50 ifi ps or the really expensive models? I can afford $50 for better performance, but the others are out of my price range.

Thanks Tim

I did the exact thing you suggested above, but in Volumio2. I could hear the difference.

While its a good suggestion my goal is to have zero digital degradation where its within my control, I prefer to disable all possible digital treatments.

If tapping into the output of Moodes volume control is not possible then I guess I would go down the separate volume control path, eg. a remote controlling a physical servo motor of some sort.

I'm guessing this would require adding a feature to Moode to allow value output reading from the volume control GUI even though its in a 'disabled' state?

Hi,

Zero-DSP configs are also fine but when MPD volume control set to "disabled" it outputs 100% volume. I think what u are describing is to have a config where MPD outputs 100% volume AND have an operational Moode volume knob but one that is disconnected from MPD and instead, through some method, drives the external volume control on your AMP.

It would take some (unknown amount of) coding but the volume knob could be disconnected from MPD and its easy to read the level setting using a simple SQL query, but I'm not sure what method could be developed to take 0-100 knob setting and turn that into commands sent to a servo volume controller on an amp.

Interesting project for sure.

I think I could work out a way to from the sql onwards, most likely a running daemon that continually queries the volume value (if it can't be pushed) then feed that to an external ardunio.

Would this feature have to be done at the MPD level, if so I'll throw a feature request that way.

Hi,

This is more of a one-off case so probably not a feature. Take a look in /var/www/playerlib.js for code that checks and sets volume. This is where some stuff needs to be commented out or logic changed so that knob changes don't actually result in volume changes being sent to MPD, and that when MPD volume is set to disabled, the knob is not automatically 0'd out.

The sql query to get the current knob setting is below. Run from ssh.

sqlite3 /var/www/db/player.db "select value from cfg_engine where param='volknob'"

Hi Tim!

2.7 works perfect for me! Even sounds significantly better- maybe actual MPD version? Don't know. Please always also keep sound quality in mind when developing;-) No issues at all! Well done!

There's only one competitor: Archphile

I'm glad, that there are at least two music player disro's, that fill my needs completely.

The teams around Volumio or Rune Audio obviously aren't able to get their own ideas to work smoothly and satisfying;-) Thank god, there are people out there, that are capable of bringing the initiator's work to life!

Keep on the excellent work!

Greetingz, Robert

Hi Robert,

Thanks for the nice compliment! Much appreciated 🙂

Archphile Mike does a fantastic job. Wish I had some of his kernel hacking skills. Maybe someday.

Hi all,

I wanted to share the script i made in order to import your radio channel in moodeaudio from Tvheadend.

If you have never heard of Tvheadend you should have a look it is also a great FOSS project. Let's you stream, record, watch TV. I am using this on osmc on a pi with 2 DVB-T dongles so this allows me to import local radios to moodeaudio UK digital radios (BBC etc..). Let me watch TV also on my tablets and pcs running KODIs.

I ordered the $50 IFI iPower unit (supposed to arrive in a week or so). At that price, I could afford to experiment. As far as I can tell, it will need an adapter cable to bridge from its bayonet connector to either a microUSB connector or to GPIO pins on the RPi, but maybe I'm just misreading the specs.

It'll probably be a couple weeks before I can post my first impressions.

Kent
