 Posted: Wed Aug 04, 2021 7:07 pm Post subject: Need a suggestion on audiophile DAC(more in post) |
 |
|
Hello my Gentoo sisteren and brotheren.
I need a suggestion.
I need a DAC that MUST work over USB2/3 and allows for mic in.
I want entry level audiophile equipment.
My budget 150-300 Euro, will consider more expensive stuff, but would rather not.
Bonus if you can suggest some entry level AMP.
Thanks!

I want something that allows me to use semi good earphones and 3.5 mic(of course i will consider cable 'converters'). I can consider cheap DAC and buy AMP separately.
AMP is dumb device, so anything goes. Unlike DAC. It has to be supported on Linux. I will 'swap' the DAC between linux and doze.(just a usb3 hub is swapped between 2 machines, so i can conveniently change keyboards/mice/webcams/DAC/etc). So it has to be USB.
I will be listening to music many hours a day. I will do occasional gaming. I will need mic for work, to participate in work meetings.
its a broad answer, but hey, I milk my PC and DAC hard...
I was thinking to get Shiit Hel, but its not available in my region ATM.
My Fulla Shiit fails on mic port otherwise would not bother changing it.

dimko,,
Without wishing to derail the topic, what do you have in /proc/asound/devices with your USB audio device connected?
I had to google Fulla Shiit before I could take the naming seriously.

| Code: | cat /proc/asound/devices
0: [ 0] : control
1: : sequencer
16: [ 0- 0]: digital audio playback
24: [ 0- 0]: digital audio capture
32: [ 1] : control
33: : timer
56: [ 1- 0]: digital audio capture |
With that said, on windows I have same issue.
2 different OS, same problem...
Mic definetly works, checked on 2 different DAC and it works there.

dimko,
You have two different input devices and one output device.
The ALSA default is sound card 0 which is
| Code: | 16: [ 0- 0]: digital audio playback
24: [ 0- 0]: digital audio capture |
Sound card 1 is input only, which could be a webcam.
What audio devices do you have connected?

I have 3 devices.
1. Webcam(crap quality, using as back up)
2. USB Shiit Fulla
3. Mobo(not sure if enabled in BIOS, no interest in using it)
I am familiar with .asoundrc.
Where I now use webcam for input and Fulla as output device.

Jaglover,
I like to poke at the system under investigation before doing any changes.
USB devices are usually one device for input and one device for output.
We have one and a half devices here, so the problem space is too large to begin to make guesses.
I don't rule out applying a soldering iron but lets see what else we can learn.

These boxes are like mixer panels, they may have several inputs, which are all mixed into one output. Which makes it exactly one capture device for OS, OS is not aware of actual inputs. And it has no output for OS. At least this is what I think it is, I may be wrong.

dimko,
OK, we see your webcam and Shiit Fulla there.
If output works, the Shiit Fulla is the default.
Open alsamixer in a console window.
Press F4 to show only the input controls,
Paste the entire window into a post.
I'll look at it in about 20 hours.

if I do F4 there - I get pulseaudio info.
If I change to Fulla Shiit - I get:
'cannot load mixer controls: Broken pipe'.
I suspect it's very simple card. It doesn't have a mixer
It has a knob for sound volume and no way to change volume in actual driver.

this problem with mic is coming and going
it drives me mad a little...
I understand if soemthing happens to my system after every reboot, but same story in windows?
When mic doesn't work in linux it doesn't work in windows same time.
And when it does - works on windows too, which makes me think it's hardware issue.

I still think this is not a full soundcard as NeddySeagoon thinks. I haven't seen this particular device, but I think it is just a sound input (capture) for computer. If any mixing or level adjusting is done it is done at analog level, in this Fulla box, and cannot controlled from computer. I have a USB condenser microphone here. When I plug it in I get this:
| Code: | 19: [ 2- 0]: digital audio capture
20: [ 2] : control
33: : timer |
Pretty much same as yours. Just plain capture input, nothing more.
Therefore, since you see this capture device in your computer I diagnose this is a hardware problem, something for soldering iron.

Jaglover,
Two USB devices ...
I wonder if its device detection order.
dimko,
Please provide /proc/asound/devices for the working and non working states.
That will eliminate (or confirm) device detection order.
I'm coming round to Jaglovers hardware theory more though.
Pulseaudio is a wrapper around ALSA and cannot work until ALSA does. It gets in the way of these investigations.

NeddySeagoon,
Order is not a problem. I can always overwrite my .asoundrc.
I have strange feeling i know what problem is.
ipc_key was not set correctly in .asoundrc. There were duplicates when it supposed to be unique.
But WHY it solved windows problem too on another PC?
does ipc_key parameter somehow defines something on USB hub i am using?(i simply reconnect hub between 2 computers)
May wanna test that hypothesis...
Yet suggestion of sound card would still be appreciated.

Jaglover,
I've seen wired jack sockets not soldered at all and badly fitted surface mount connectors of all shapes and sizes with failed joints because the thermal mass of the connector prevented the solder paste reflowing properly, and as you say, getting in there with some real tin/lead solder and an iron fixed it :)
dimko,
My detection order suggestion was based on the sound card detection order not being fixed from boot to boot. Its not.
The first detected card is card 0. Changing .asoundrc is not a permanent fix. Only until the order changes again.
Audiophile quality restricts you to an analogue system, end to end ... be that's a fruitless discussion so I'll state my opinion and leave it at that. :)

Nope, Problem happened again. I swap devices in asoundrc and i can hear other USB mic from webcam.
Changing IPC did not change either.
