I'm trying to make DAC+ DSP as an audio receiver for TV.
But I cannot get stable result at this moment with several problems.
I'm using RPi 3 a+ and DAC+ DSP. No other hardware.

1. I have to set DSP profile every boot.
I read some posts in the forum and did the step to write the profile for selfboot.
The steps I did were;
- Power off then unset the selfboot jumper
- Power on then write the DSP program 12 from HifiberryOS Web UI
- Power off then set the selfboot jumper
- Power on
But I still got "Unknown Program" after power cycle and need to program again.
Are there missing steps I need to do?
2. No analog audio
And I cannot get any analog audio output. Based on the article about the linux kernel version, I added "force_eeprom_read=0" to get correct driver.
However, strangely, I got analog output some, but it was very rare and went silent again after power cycle even in that case.
Mostly I haven't got any output except popping noises while programming the DSP from the web UI. For example, I cannot hear anything from "play -n synth sine 1000"
I cannot get why it doesn't work stable and where the root cause is, software or hardware.
Please give any advice.
