SSL2.conf Defines Incorrect Number of Capture Channels

SSL2.conf Defines Incorrect Number of Capture Channels

[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #676 was opened from TheBakedPotato:

The file at `ucm2/USB-Audio/SolidStateLabs/SSL2.conf` has the line
```
Define.DirectCaptureChannels 4
```
However, I believe that should actually be 
```
Define.DirectCaptureChannels 2
```
since the SSL2 (**not** the SSL2+) only has 2 physical inputs. 

As well, now, with that change, a third audio "profile" appears ago for the SSL2 output device of `Direct SSL 2`.

The `[ALSA UCM error]` still appears, but now the correct "profile" is available. As well, now my music player, Amberol, is able to persist the volume change between songs. Before if I changed the volume and proceed to the next song the audio in the Amberol application would get set to max.

The output in `journalctl` is still present

```
if the HiFi profile is selected. I'm assuming because the file `SSL2-HiFi.conf` needs to be updated for the correct number of hardware capture channels.
