BETA: piCorePlayer6.0.0 - PI4 support

[eliottinthesky]

I want to get mono on my left chanel

-> Does Mono option apply Mono (left + right) on each chanel ? Do i change the volume of right chanel ?

-> What is swap option ? just invert left and right ?

-> And what is the other option (hw hw plughw, card 0 1)

thx by advance !

With upgraded firmware, the heat is better on the PI4, but I still wouldn't put it in a sealed case, it needs some sort of ventilation

Thanks Paul,

Guess I'll put it on the back burner for the time being as the only problem I have is slow samba transfers from my ripping pc.

Mono mixes both channels into one, but not sure if it comes out left or right or both.
Likely you want to run plughw

Card 0 is the onboard rpi audio, card 1 is your i2s dac. If you disable the onboard audio, then you i2s card will be card 0.

Adding the following to the end of /etc/asound.conf would create two new output devices called left and right which downmix stereo to mono.

You will need to adjust the hw:0,0 to hw:1,0 depending on the location of your DAC as Paul has already outlined. Don't forget to backup your configuraton before you reboot otherwise the changes will be lost.

pcm.left {
        type plug;
        slave.pcm "hw:0,0"
	ttable {
		0.1 0
		0.0 1
		1.0 1
		1.1 0
	}
}

pcm.right {
        type plug;
        slave.pcm "hw:0,0"
	ttable {
		0.1 1
		0.0 0
		1.0 0
		1.1 1
	}
}

Then configure squeezelite output device to left. You can even run a second mono instance of squeezelite to the other output device right.



I use these test files to confirm that the left and right channels are downmixed correctly.

Pi 4 4GB,USB DSD DAC ESS9038Pro+Amanero combo 384 with picoreplayer 6.0.0 beta6 works well,the audio quality is better than my pi 3B,micro SD boot is no problem but USB flash drive and USB SSD HDD.

Grasping at straws here. I have a Pi 3B+ which I had used with pCP 5.0 reasonably successfully with a UE BOOM 2 speaker.

Now with 6.0 I find that the speaker cuts out, presumably from weak signal, in places it worked very well before.

Is it possible the BT power is lower in 6?

All else here has remained the same - location of Pi, power supply, no new impediments to the signal path etc., but I can't get the speaker to work where it used to.

Thanks...

The only difference is in bluetooth is the front end software. Bluez, and bluealsa are identical between 5 and 6. Are you running WiFi. The only way to get true trouble free WiFi and Bluetooth, is to use a 5Ghz WiFi channel.

Thanks. I turned off wifi as a wired connection is available. Now all is well.

Just pushed up b7, main thing with this release is added a mirror repo (sourceforge) for downloading packages. See OP.

This will likely be the last beta, and will move to full release.

Thanks Paul, P4 updated to b7, tabs at bottom of page seem fixed.

Just one thing noticed this last couple of updates - the warning during update (light skin) is unreadable.
