Re: Virtual Sound Card?

David Rhoads
 

Hey Jason,

I don't know if you have heard of Jack. I have been fiddling with it a little lately for audio production work. It somehow acts as an interface between pulse audio and the applications. Then there's an application called jackctl I believe that lets you select which applications to send the audio to. I'm not sure if this would work for ham radio, but it's probably worth a shot.

Unfortunately the wiki write up is missing at https://nw-digital-radio.groups.io/g/udrc/wiki/home
but it is based on the information here https://github.com/nwdigitalradio/split-channels
Read up on pulseaudio and create multiple instances in asound.conf

A "tar" file is still compressed like a zip file. You need to un-compress it to get the image file for Etcher. In Windows, I like PowerArchiver, as it un-"zips" many compression formats. I'm sure there are other tools that can do it (native tools in Linux) in Windows, etc.

Ok, slowly making some progress after numerous download fits and starts. All this in MacOS 10.15.1

Got a copy that was compressed in bzip2 and managed to get it to uncompress from the command line which resulted in a .tar file. Simply double clicking the file seems to decompress it but the resulting file does not work in Etcher.

GalenaEtcher does not seem to know what to do with the .tar file (18.36 GB). When trying to make the image selection the .tar file is light grey and cannot be selected.

This is such a great idea, I hope I can file flashed onto the SD card.

Etcher should be able to read the .tar.gz file directly if I recall... so you have a couple of choices:

1:---------------
gzip filename.tar # <turns it back into a .tar.gz
open with etcher and burn
or 2:--------------------
tar -x filename.tar # <turns it into a raw disk image
open with etcher and burn

Perry,

Yes, as I said, USB drive I/O will be much faster than an SD card. even if it is a "regular" HD and not a solid state drive.  I could go on and on but no one wants to hear my rants.  :)

The Raspberry Pi was designed for experimentation, so do what you feel you want to do, and learn as you go!

Most of the people going to “disk” storage are using a small (120/240 Gb) SSD in a USB 3.0 housing.  You will see improved boot times and better overall response.

Now-a-days, SD cards are pretty robust so there is no need to buy an extra USB hard drive.  That only makes it harder to power the Pi as you also need to provide power to the HD.

 

If you use Class 10 SD cards, or U1-3, you will have years of hard use.  I have a Class 10 32GB SD card I have been using for nearly 4 years in my development Pi and it still works perfectly.  I've also had hard drives that last years and years, and some that fail quickly.  That's why I back everything up regularly.  I recommend Class 10 cards for all my projects and no one has every had a failure that I am aware of.  That is all I use.

 

Of course, the fastest SD card can't compare to the speed of a USB 3.0 disk drive for I/O, but let's face it....the vast majority of what we do with the RaspPi's will never need those speeds.  10MB/s is still pretty fast.

 

In every situation I have seen, you still need an SD card in the Pi to boot from, and then you can configure it to switch to the USB drive.  I don't think the Pi 4 is any different.

 

Something else to consider, my Pi3's run about 20 degrees cooler than the Pi4, which seems to just be a hotter device.  I installed a set of those cheap Internet cooling fins and it didn't make any difference.  A case with a fan might be required on these, especially if you are intending to drive it hard. Something else to consume power.

 

Just my 2 cents.

I will be placing my order for the Pi4 with the 4GB memory. I will be looking at the time of order what will

be available for loading I may be able to order a disk at that time. .

I have seen mention of using a more robust USB disk that can be configured to be root disk is there information on this option or what is you opinion of this?

Hi Marty,

32GB Micro SD cards are available for just slightly under $10, or less than going out to lunch (around where I live anyway).

Good luck with the download and install!

Please remember to read the README.TXT. It has some important info, like why the "network doesn't seem to work".

That hint saved a lot of Googling. So the wifi hotspot password is “1234567890”.  And in that file is the WiFi country that defines your channels. The comment tells you to edit if you are not in GB.  But of course it has already been changed to US.  Remember to set up locale and time zone if not in US.  Not picking up time from internet yet, clock seems to pick up from when the image was created.

Coming in late so excuse me, but you HAVE put all the bootcode bins etc from the root directory of the regular rasbian distro for the 4 to that one right?

just a thought as running on a 4 without the rpi4 bootcode in the fat section would cause it not to boot

Walter,

Stupid question but did you 'burn' the file as xxx.img so there is one
file on the SD card or did you use something like etcher to turn the SD
card into a disc with (I expect) 2 partitions on?

Just asking to be sure there is no confusion ...

I will be working on a v3 image, but likely this will take a couple of months to develop. I will focus on decreasing the overall size of the image while retaining functionality. And I will also focus on an automated, rather than manual build process. Like I said, this will take a couple of months to develop, because it has to be done on my free time.

Just as long as you don't modify it (other than compression), I am ok with it.

Hi Edward.

Offhand, the easiest way is to reboot, as the "KillHotspot" bash alias is only temporary. I hadn't thought about including something to re-enable it.
