Hi All,

I am trying vsnd from xen-troops with xen 4.13 and Linux 5.4, but domu reports:
aplay compl.mp3
ALSA lib ../../../alsa-lib-1.1.9/src/pcm/pcm_direct.c:1156:(snd1_pcm_direct_initialize_slave) slave plugin does not support mmap interleaved or mmap noninterleaved access
ALSA lib ../../../alsa-lib-1.1.9/src/pcm/pcm_dmix.c:1120:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:828: audio open error: Invalid argument

When executing aplay in domu, dom0 side log:

My xl.cfg:
    vsnd = [
        ['CARD, short-name=Main, sample-formats=s16_le;s8;u32_be',
            'PCM, name=Main',
                'STREAM, unique-id=alsa<hw:2;0>, type=p',
                'STREAM, unique-id=alsa<hw:2;1>, type=c, channels-max=2'
        ],
    ]

The audio device on my board:
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: imxaudmix [imx-audmix], device 0: HiFi-AUDMIX-FE (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: imxaudmix [imx-audmix], device 1: HiFi-AUDMIX-FE (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: cs42888audio [cs42888-audio], device 0: HiFi cs42888-0 [HiFi cs42888-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: cs42888audio [cs42888-audio], device 1: HiFi-ASRC-FE (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: wm8960audio [wm8960-audio], device 0: HiFi wm8960-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Is there something wrong in my configuration?

Thanks,
Peng.

I have CCed Artem who should be able to point to the author of vsnd.

Same issue.
aplay hu01_48k.wav
ALSA lib ../../../alsa-lib-1.1.9/src/pcm/pcm_direct.c:1156:(snd1_pcm_direct_initialize_slave) slave plugin does not support mmap interleaved or mmap noninterleaved access
ALSA lib ../../../alsa-lib-1.1.9/src/pcm/pcm_dmix.c:1120:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:828: audio open error: Invalid argument

Is there any limitation with current vsnd? Is there any plan to upstream libxenbe and snd_be
to xen?

Thanks,
Peng.

Hi Peng,

When you use ALSA as sound backend on Dom0, HW parameters introduced
in xl.cfg must match ones that real HW has, e.g. format, rate, num channels,
buffer size.

1. You could check your real HW by playing the file on Dom0:

 aplay -D hw:2,0 sound.wav --dump-hw-params

See supported formats, channels, rate and buffer in bytes.
Then update xl.cfg accordingly.

Also make sure that aplay works as expected on your Dom0.

2. I don't see any errors in the sndbe log, could you provide log with place
    where the error occurs.

3. You can use pulseaudio as sound backend on Dom0. Pulseaudio doesn't
require exact matching of real HW params.

-- 
Best Regards,
Oleksandr Grytsov.
