Can you record something with the card anyway?
Try with:
arecord -D default -f cd -t wav test.wav
Or
arecord -D hw:1,0 -f cd -t wav test.wav
Does it say that it is recording data and is the test.wav file created?
If recording works then I really need a log file in order to see what is going on.
Dear Jan
Many thanks for your continued support. I ran the command and it said that it was recording. I used Ctrl-C to stop recording. I then manged to copy the test.wav file onto a USB stick and I could play the wav file and hear that it was successfully recorded. Please find log file contents below.

The log file confirms that the issue is ALSA related:
2020-12-04T17:44:12.003Z liquid-stdout: [threads:1] Thread “input.alsa_7224” aborts with exception Alsa error: No such file or directory!
This was also the case with the first command containing the -D default option?
Dear Jan
Yes it was with the first command
arecord -D default -f cd -t wav test.wav
Best wishes
Since the initial release of Entrypoints I especially got feedback about the Audio Entrypoint. The experiences from @CrystalGipsy, @Todd_Haugen and @Ian_Foulger helped me in working on the weak spots of the initial implementation. Thanks guys for your input!
This release contains some of the “finetuning” I was talking about in the initial post.
The biggest change is that in the Settings screen of the Audio Entrypoint you have to select the soundcard that has to be used. Last weekend I discovered that using the “default” audio device is causing high CPU loads, by specifying a specific device the load drops very significantly. As an example, on a Raspberry Pi 2B the load dropped from a single core load of 95% to 10% while capturing a 44.1 kHz, 16 bit signal.
@CrystalGipsy, this might have caused the difference in performance you saw when you compared the Entrypoint with your own Liquidsoap experiments. Might be worth a retry 
@Ian_Foulger, I hope that the new soundcard selection solves the problem you are facing, let me know.
Another point is the manual actions that had to be performed to have the stream active and be able to setup the radio stream in Roon. Here I made some improvements to have it active as much as possible, only if the soundcard has specific limitations that prevent this (like the blocking behavior of the HiFiBerry Digi+ I/O) then a manual action is required. For the HiFiBerry DAC+ADC, that I acquired for testing, you now only have to activate it once in the Settings and after that it will stream what you feed into it, or silence.
Here is a screenshot of the new Settings dialog:
If the Extension Manager has auto update enabled then the changes will be pulled in the next time the update is performed. It is also possible to update manually via the Settings dialog of the manager, select the Audio Entrypoint from the Entrypoints category and perform the update action.
Is this compatible with RoPieee or would I need to add a second Raspberry Pi with DietPi installed on it if I wanted to use this?
Great news, Thanks
\
No Ropieee cannot run extension manager or install extensions other than its own display one.
The single Pi solution would be to install DietPi and run Entrypoints and Roon Bridge side by side. With this you will lose the RoPieee specific features.
Please tell me (again) why we can’t have hires S/PDIF input into Roon so that I can use HAF filters in the convolution engine for such a (digital) source.
Great work Jan will give it another try when I get chance.
Got this setup encoding and streaming at 192/16 sounds pretty damn good. 24bit would be the icing on the cake as I think thatw where the real advatages are over the sample rate. But this works really well.
@Jan_Koudijs I wonder if the issue with using ffmpeg is similar to that of liquidsoap. You can get ffmpeg to output a stream to icecast easily and this supports higher bit depths but it seems to max out the cpu, looking at top whilst is capturing it at 100% and suffers from alsa buffer xruns and drops out all the time even though the stream is consistent. I cant find anything online to get arounf why its so high.
ffmpeg -ac 2 -f alsa -thread_queue_size 1024 -i hw:0,0 -acodec flac -ac 2 -content_type audio/ogg -f ogg icecast://source:hackme@192.168.1.203:8000/entrypoint-audio-DietPi
Great to hear that the higher sample frequencies are now also working in your setup.
(TL:DR I’m not a troll, I promise!)
Hello Jan. This is going to sound like it’s from way out in left field so I’ll start by apologizing for being totally ignorant of Roon until I just read all the comments in this thread, along with your GitHub wiki. But I ran across your amazing-sounding extension here and thought it would be an amazing complement to what I just developed. I took a pair of 300-disc Pioneer CD changers and wrote a Pi-based Python app to remote-control the changers, using a MySQL database of CD info, cross-referenced to disc slot number in the changers, so that a web browser (and eventually an Alexa voice interface) can load the desired CD and control playback – basically, anything the changer’s IR remote can do.
So, I’m thinking I can now tie this into your work and stream the result, using your Audio Device input interface. My question (finally ;-): Do you think I could hack your web interface such that I could incorporate my own controls for disc selection, selecting titles from my database, and player controls? And as a side note, and separate need – I haven’t yet loaded my 600+ discs into my database. Do you have any suggestions on how to capture that metadata into a local database without going thru the laborious and time-consuming ripping process?
Jim, you don’t actually have to rip the CDs to get the metadata, but the fastest way to do it is to put each of them into a CD drive to look them up in an online DB. Python Audio Tools, for instance, has a program “trackinfo”, which will list all the metadata for the tracks of a CD.
Dear Jan
Success! Sorry that I have not responded sooner, I have not had time to try V0.2.0 until this weekend. Anyway after update I was forced to choose a soundcard, I choose ‘Codec USB Audio’ as that is all that was shown as an option. It then informed me that no audio was being played, so gave it a source, confirmed it was playing in Icecast2 server browser window. Then setup Radio station as per your instructions and it’s all working!
I am very pleased, thank you so much for you support and help 
So if I understand you correctly you want to convert the output of the cd changer into a web stream without any Roon integration. If that is the case I suggest that you look into Icecast and Liquidsoap as that are the 3th party components I use for the actual web streaming, links are in this post.
Thanks, Bill, for the suggestion – I hadn’t seen this one. Every tool I’ve found for this also rips by default & I haven’t found a way to just grab the info without first having a file created & then extracting its properties. I can’t wait to try this trackinfo program – thanks again!
Jan, actually no – I thought I would be integrating my CD changers into Roon. I just wanted to also include my disc selection and playback controls in the integration, since Roon wouldn’t be able to control my hardware. But if you don’t think I should or need to use Roon then I’ll look into these programs you mentioned. Thanks.
