Loopback device respond to changing parameters on the other end.
by alsa＠scripple.org 05 Oct '20

05 Oct '20

Hello, Let me open by saying I am not an experienced ALSA developer so hopefully I'm just missing something really easy here. I'm trying to use some DSP programs that insert themselves into the audio chain via the ALSA loopback device. My understanding is that whichever program opens the loopback device first sets the parameters, so the DSP program has to know what parameters any playback program is going to use before it opens its end of the loopback device. And it has to know when to release the loopback device so that another (or the same) playback program can open the loopback device with possibly different parameters. (The DSP program also needs to the know the audio parameters just to do the right thing of course.) I'm not sure how best to accomplish this. I don't want any form of auto-format conversion such as using a resampling or format conversion plugin. I want the DSP program to access the raw PCM stream however it was configured by the playback program. I was thinking I could use the PCM hook system to accomplish what I want. Capture the SND_PCM_HOOK_TYPE_CLOSE (and possibly even use the hook init) to tell the DSP program to close its end of the loopback device. Capture the SND_PCM_HOOK_TYPE_HW_PARAMS to configure the DSP program with the appropriate parameters and tell it to open the loopback device with those new parameters. The init/close part is easy, but I can't figure out how to access the hw_params about to take effect from inside the hook function. If I'm understanding the code correctly the hook function is called from _snd_pcm_hw_params_internal before the PCM interface is actually setup. And snd_pcm_hooks_hw_params chooses not to pass the snd_pcm_hw_params_t structure to the hook function itself, only the snd_pcm_t handle. But since the snd_pcm_t hasn't actually been configured I don't see how to get the new hw_params from it. The hook system does set the new hw_params on the pcm private_data/generic slave device, but I'm not sure how to access that from just libasound2. (Meaning without the full alsa_lib set of includes that define _snd_pcm and such.) I really hoping one can access snd_pcm_hw_params_t inside the hook function. It seems the information really should be there given the callback is triggered by a change to those parameters. Alternatively, is there a better way to automatically configure the read end of the loopback device to match the parameters of the write end? (One that doesn't required modifying every playback program to announce their intentions to the DSP program.) Thanks, scripple
