[Alsa-user] Low volume from "ALC888-VD Analog" device

2020-02-18 Thread D. R. Evans
I recently bought a system with a Supermicro MBD-X11SAT-F-O motherboard, which includes audio. Previously, this system ran Windows; it is now running debian stable (buster). Unfortunately, the audio seems to have very low output. I have fiddled with all the high-level controls available through

[Alsa-user] automatic rate conversion on record

2020-05-22 Thread D. R. Evans
I have an Intel device that provides a sample rate only of 44100, but I want to record a stream at 8000. The hardware device is: hw:0,0,0. As far as I can tell, this is "easily" doable with a plugin, but I haven't been able to make it work (this is the first time I've tried to use a plugin).

[Alsa-user] documentation for error codes?

2020-06-05 Thread D. R. Evans
Many functions say about the return value: 0 on success otherwise a negative error code Where is the documentation for the various possible "negative error code"s? I am seeing a -32 under a specific set of circumstances, but don't know what that returned value means, or even what header value

I have spent most of the past couple of days trying to understand why a program is failing to obtain data from a device. I have stripped away the code down to this very simple (and silly) sample: cout << "avail +5s = " << snd_pcm_avail(_handle) << endl; cout << "calling
