Thanks, snd_pcm_recover() worked well after s2ram.

[Alsa-user] snd_pcm_hw_params_set_buffer_size returns -EINVAL

2016-09-26 Thread Johannes Lorenz 
Hello,

this happens in [1]. You can also call snd_pcm_hw_params_set_buffer_size() 
before snd_pcm_hw_params() (that's probably better?), it always results in (-
EINVAL).

The google-answers did not help. Any idea? In my case, the buffer size is 256, 
but it also fails is I use 32768.

Thanks on advance!
- Johannes

Bob, what connects your computer to your TEAC?  A USB cable?

What music player do you use?

What is the output of "aplay -L" in a terminal window?

If that is the case then I do not understand the documentation which states:

This document describes standard names of mixer controls.
  
  3 Syntax: [LOCATION] SOURCE [CHANNEL] [DIRECTION] FUNCTION
  4 
  5 DIRECTION:
  6(both directions)
  7   Playback
  8   Capture
  9   Bypass Playback
 10   Bypass Capture

I feel like I am missing something here.

In the "simple" mixer API, controls are either playback or capture.
Having both would imply that there were two independent switches.

Sorry, forgot to say that alsamixer just shows a single playback
control called 'Digital In', but the control is unresponsive.

That documentation describes the names of mixer controls in the kernel,
which corresponds to the control interface.

The simpler mixer interface is an abstraction layer on top of that.

Use "amixer contents" instead of "amixer scontents" to use the
control interface.

I would take this step by step.

First you should use aplay to find out what works and what doesn't.  Find a
.wav file of representative music somewhere or create one (use
soundconverter for instance).

Run "aplay -l" to make sure that your TEAC card is card 1 (it looks as
though it is but check)

Then try playing the resulting .wav file with aplay through the TEAC, like
this:

aplay -D hw:1,0 mysong.wav

(this will play at full volume if it works so make sure you have your
volume turned way down)

If that doesn't work, try

aplay -D plughw:1,0 mysong.wav

Assuming one or the other of those works...

Second, is the TEAC dedicated to MPD's use, or will you want other programs
to use it (like VLC)?

Assuming it's dedicated, then I would configure MPD to talk directly to the
TEAC through ALSA, especially if you have music at varying bit rates and
you want to pass them through untouched.

I run two music servers in my house, both with MPD and dedicated DACs.  My
audio output stanza in my /etc/mpd.conf looks like this:

audio_output {
enabled "yes"
type"alsa"
name"Schiit Bifrost"
device  "hw:2,0"
mixer_type  "disabled"
auto_resample   "no"
auto_channels   "no"
auto_format "no"
dop "no"
}

You would have to change the name and the device.

If the aplay experiments didn't work or you don't want to dedicate, then
get back to the list.

[Alsa-user] TEAC CR H101DAB receiver not seen as a sound device

2016-09-26 Thread Bob Williams 
Hello,

I have recently purchased a TEAC CR H101DAB receiver which can receive
USB input from my computer. My operating system is openSUSE Leap 42.1
with kernel 4.1.31-30-default. I am using pulseaudio.

YaST does not see the H101 at all, but alsamixer does. It reports
itself as TEAC USB AUDIO DEVICE.

You can use one device from multiple threads, but all function calls
must be serialized.

No.  When you get -ESTRPIPE, the stream was suspended, and all you have
to do is to reinitialize it with snd_pcm_prepare() or snd_pcm_recover().
