headers: make more headers self-contained

alsa-project/alsa-lib pull request #435 was opened from timblechmann: Some IDEs parse headers in isolation to populate their code model. This exposes some missing headers, mainly for alsa internal struct definitions, ssize_t (requiring sys/types.h), size_t (requiring string.h), va_args (requiring stdargs.h) or FILE (requiring stdio.h) This patch makes the main headers parsable by qtcreator Request URL : https://github.com/alsa-project/alsa-lib/pull/435 Patch URL : https://github.com/alsa-project/alsa-lib/pull/435.patch Repository URL: https://github.com/alsa-project/alsa-lib

This device has 3 virtual stereo channels out and 4 virtual stereo channels in as follows: ![out](https://github.com/user-attachments/assets/f4cacf14-e75e-4d33-ad64-cca4ca7ee18e) ![in](https://github.com/user-attachments/assets/60515091-51a5-4299-97c7-a12d3c091b8a) Microphone inputs have been separated to two mono channels for convenience. As far as I can tell, the [Universal Control](https://www.presonus.com/pages/support-documents-downloads?product… software is required to configure levels and effects of these channels, but the settings can be saved to the device and operation without the software is possible outside Windows.

Missunderstanding or a BUG in reported frequencies for audio cards present in system.

alsa-project/alsa-lib issue #432 was edited from CapSel: I use ArchLinux with kernel 6.12.7 with "Zen" patches. HW is ASUS Vivobook 14X pro. So the problem I'm having is that I can't set pipewire to 96000 sampling rate. I tried all options in pipewire. Nothing helped. But a long time ago it worked fine - I can't remember when (at most week after Baldur's Gate 3 release ;). What I see in system: when I do `cat /proc/asound/card0/pcm3p/info` (no other pcm* files) I can see `name: HDMI 0` - it's important. with `cat /proc/asound/card0/codec#0` on top there is: ``` Codec: ATI R6xx HDMI Address: 0 AFG Function Id: 0x1 (unsol 0) Vendor Id: 0x1002aa01 Subsystem Id: 0x00aa0100 Revision Id: 0x100700 No Modem Function Group found Default PCM: rates [0x70]: 32000 44100 48000 bits [0x2]: 16 formats [0x1]: PCM ``` for the other (default) audio card: `cat /proc/asound/card1/pcm0p/info` (there is pcm0c file too but I did not check it) gives: `name: ALC294 Analog` `cat /proc/asound/card1/codec#0` on top: ``` Codec: Realtek ALC294 Address: 0 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x10ec0294 Subsystem Id: 0x10431ab2 Revision Id: 0x100004 No Modem Function Group found Default PCM: rates [0x560]: 44100 48000 96000 192000 bits [0xe]: 16 20 24 formats [0x1]: PCM ``` so as you can see: - hdmi supports up to 48000 - analog supports up to 192000 I first noticed there is something wrong with alsacap program that reports: ``` *** Scanning for playback devices *** Card 0, ID `Generic', name `HD-Audio Generic' Device 3, ID `HDMI 0', name `HDMI 0', 1 subdevices (1 available) 2..8 channels, sampling rate 32000..192000 Hz Sample formats: S16_LE, S32_LE Subdevice 0, name `subdevice #0' Card 1, ID `Generic_1', name `HD-Audio Generic' Device 0, ID `ALC294 Analog', name `ALC294 Analog', 1 subdevices (1 available) 2 channels, sampling rate 44100..48000 Hz Sample formats: S16_LE, S32_LE Subdevice 0, name `subdevice #0' ``` As you can see: - hdmi supports up to 192000 - analog supports up to 48000 so it's... flipped? here is a output from `cat /proc/asound/pcm`: ``` 00-03: HDMI 0 : HDMI 0 : playback 1 01-00: ALC294 Analog : ALC294 Analog : playback 1 : capture 1 ``` To confirm this I downloaded flac file with 96000 sample rate and tried to play it with ffmpeg after pipewire,pipewire-pulse,wireplumber services are stopped. I confirmed that these programs are disabled by checking if `ps ax | grep wire` before and after, also I monitored logs from these services. It reported error for device "hw:1,0" because it could not set sampling rate to 96000. It did not fail on "hw:0,3" but of course I did not hear anything since external monitor is disconnected. Replay command: `ffmpeg -i yuri_korzunov-through-moon_ring-96kHz-24bit.flac -f alsa hw:1,0` the file is some random file found in internet that tested with `ffprobe` shows that it has sample rate of 96000. I don't want to attach it since I forgot where I found it ;) I don't have `asound.conf` files in `/etc/` or `~/.config`. After connecting external monitor alsacap reports max 48000 for both cards. FFmpeg reports sampling rate problem with both audio cards: ``` [alsa @ 0x586316542b00] sample rate 96000 not available, nearest is 48000 ``` I had this monitor connected before and alsacap reported "flipped" results - not like now that both cards are limited to 48000. What else can I do to discover the problem? Issue URL : https://github.com/alsa-project/alsa-lib/issues/432 Repository URL: https://github.com/alsa-project/alsa-lib
