Unfortunately I get a segfault on my system:

$./scarlett-mixer

Same for 18i20

mauropasse commented 4 years ago

@david0 I have the same issue and backtrace as you. I have the Scarlett 18i8 USB 3rd gen, but this repo should support only 1st generation. Question, if I get a Windows machine and do the configs there, will they mantain those configs when I use it with linux?

Question, if I get a Windows machine and do the configs there, will they mantain those configs when I use it with linux?

At least for me it is preserved. This is how I currently use 18i20 in Linux.

P.S.: mine is 2nd gen.

hires commented 4 years ago

I can confirm my 18i20 2nd gen also segfaults.

[1]    152104 segmentation fault (core dumped)  ./scarlett-mixer -vv --print-controls
david0 commented 4 years ago

I found the problem. With gen2 the mixer is disabled by default. You see that in dmesg:

Focusrite Scarlett Gen 2 Mixer Driver disabled; use options snd_usb_audio device_setup=1 to enable and report any issues to g@b4.vu

in my case (18i8 2nd gen) it needed the following (in /etc/modprobe.d/scarlett.conf): 

options snd_usb_audio vid=0x1235 pid=0x8215 device_setup=1,1,1,1

./scarlett-mixer -vv --print-controls now shows:

caught signal - shutting down.

The GUI looks as follows: image

The labels for the rightmost three outputs should be Headphone 2 R, S/PDIF, S/PDIF I think

x42 commented 4 years ago

OK, so there's a bit of a layout problem with the output assigns, but it now works in general?

Comparing this to https://github.com/x42/scarlett-mixer#screenshot the 8 L/R assigns should be grouped below the 4 output knobs (Monitor, Headphones 1,2).

david0 commented 4 years ago

Yes it works in general. Besides the layout, it would be nice if the "Source" column would be filled with something useful by default (all set to Off after starting). Also I think it would be better to use combo boxes. Its a little bit annoying to use these spin boxes with 40+ entries not knowing what comes next.

JCruk commented 4 years ago

Where can I get the driver? I didn't have a scarlett.conf in /etc/modprobe.d/, so I created one, but still get the same segfault core dump

The driver is the one that is build-in into the the kernel. Since you see all these outputs it seems to be a different problem than I had, maybe because you have the 18i20 and I have 18i8.

battlemaul commented 2 years ago

When you edit /etc/modprobe.d/scarlett.conf you have to insert the right device id (i my case it's 8204)

lsusb | grep Focusrite Bus 003 Device 003: ID 1235:8204 Focusrite-Novation Scarlett 18i8 2nd Gen

sudo nano /etc/modprobe.d/scarlett.conf and insert : options snd_usb_audio vid=0x1235 pid=0x8204 device_setup=1,1,1,1

JCruk commented 2 years ago

I've tried many different configurations for a 2nd gen 18i20

sudo nano /etc/modprobe.d/scarlett.conf and insert : options snd_usb_audio vid=0x1235 pid=0x8204 device_setup=1,1,1,1

to

sudo nano /etc/modprobe.d/scarlett.conf and insert : options snd_usb_audio vid=0x1235 pid=0x8204 device_setup=1,1,1,1,1,1,1,1,1

but I always end up with a dump: scarlett-mixer: ./src/scarlett_mixer.c:603: get_enum: Assertionsnd_mixer_selem_is_enumerated (c->elem)' failed.`

aclark4life commented 2 years ago

@JCruk Can't tell from your comment if you confirmed the scarlett is enabled before running the mixer e.g.

dmesg | grep -i -A 5 -B 5 scarlett

Via https://askubuntu.com/questions/1393120/how-to-enable-focusrite-scarlett-4i4-gen3-mixer-on-ubuntu-studio-20-04-3.

And if not enabled, make sure kernel >= 5.14 else you'll need to compile kernel module from https://github.com/Focusrite-Scarlett-on-Linux

Assuming everything above for gen3 applies to gen2 too ... :shrug:

Justin-Hoffman commented 1 year ago

I have an 18i20 gen 3 ( vid=0x1235 pid=0x8215 ) that seems to have similar issues to the 18i8 gen2.

Initially I was segfaulting when loading mixer controls because, as with the gen2, I needed to first enable the mixer driver via modprobe options.

I'm now segfaulting when setting up high-z UI elements (I think the Pango warning is irrelevant, I'm on Fedora 37 workstation):

`$ ./scarlett-mixer

(process:6537): Pango-WARNING **: 10:39:35.343: Invalid UTF-8 string passed to pango_layout_set_text()

(process:6537): Pango-WARNING **: 10:39:35.346: Invalid UTF-8 string passed to pango_layout_set_text() Segmentation fault (core dumped) `

The backtrace was:

`#0 0x0000000000421139 in get_enum (c=0x6c65ddb00) at ./src/scarlett_mixer.c:737

Line 737 is an assert:

assert (snd_mixer_selem_is_enumerated (c->elem));

I can't dereference c:

(gdb) p *c Cannot access memory at address 0x6c65ddb00

That address is the result of a call to hiz(ui, i) at the call line of the outer function, line 1383:

robtk_cbtn_set_active (ui->btn_hiz[i], get_enum (hiz (ui, i)) == 1);

I have little experience with robtk and/or the mixer driver and I'm not sure where the fault is here but I'll see if I can drill down further later this week.

The issue is that the controls mapping for earlier generations isn't compatible with the later generation devices (18i20 gen2 appears to have 260 controls per above, the 3rd gen has 436) and any alsa API calls requesting controls by index when using an incorrect mapping return unexpected control types. Reading many other issues here on github I realize that this probably the root problem for a half dozen of them (control mapping from older generation hardware used with newer hardware).

The issue I encounter when writing a patch to fix this is that we identify the configuration by comparing the card name returned from ALSA: const char* card_name = snd_ctl_card_info_get_name (card_info); ..then a few lines later... for (unsigned i = 0; i < NUM_DEVICES; i++) { if (!strcmp (card_name, devices[i].name)) ui->device = &devices[i]; }

The card name reported by ALSA seems to be the same for any 18i20 across all three generations, but the control configuration is incompatible amongst these generations. If we put together the mapping for gen2/gen3 devices, we would need to use a different or additional method to identify the card in a way that discriminates between hardware across generations.

@x42 - Would you accept a patch that adds a mechanism to further differentiate between generations of hardware that report the same name from the ALSA api? I believe I could work this out by reading /sys/class/sound/card[device_number]/device/modalias to pick out the vendor and device IDs, but I would need to dig these up for each supported device.
