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

Subdevices: 1/1
Subdevice #0: subdevice #0

Subdevice #0: subdevice #0
card 1: cs42888audio [cs42888-audio], device 1: HiFi-ASRC-FE (*) []

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.

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. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel ^ permalink raw reply [flat|nested] 7+ messages in thread
