Hi,

½ a year ago I started using the following .asoundrc in my home folder
to automatically access HDMI audio after log in on a plain ALSA (and
jackd, but no pulseaudio) install.

[rocketmouse@archlinux ~]$ cat .asoundrc
defaults.pcm.card 3
defaults.pcm.device 7

Unfortunately I can't start jackd to access another device anymore, but
since I'm doing almost all pro-audio related work with Apple, the crappy
display's speaker sound is usually ok for the Linux machine.

To access another device I need to 

[rocketmouse@archlinux ~]$ mv -i .asoundrc .asoundrc_disabled

then log out and in again to use one of devices in alsa-base.conf or an
USB device.

[rocketmouse@archlinux ~]$ cat /etc/modprobe.d/alsa-base.conf 
# ALSA module ordering
options snd slots=snd_hdspm,snd_ice1712,snd_ice1712

I've done the mv and log out and in right now for the very first time.
At least there's no need to reboot :D.

Regards,
Ralf

Hello all,

Copying from Clemens Ladisch's reply to James Cloos[1]
this asoundrc plays via the HDMI output:

pcm.!default {
 type asym
 playback.pcm "plughw:CARD=PCH,DEV=7"
}

Thanks for supporting this forum.

[Alsa-user] Setting a PCM as default device

2022-04-20 Thread Joel Roth 
Hi Alsa users,

I previously asked this question on Linux Audio Users list. 
Since no one could help, I'm posting here.

I'm able to play sound with this command:

aplay tmh.wav -D plughw:CARD=PCH,DEV=7

I would like to make this the default device in asoundrc.

I tried this asoundrc:

pcm.hdmi_out {
  type plug
  ipc_key 5641 
  slave {plughw:CARD=PCH,DEV=7 }
}

pcm.!default {
  type dmix
  slave { pcm "hdmi_out" }
}

Then trying 'aplay tmh.wav' results an error:   

  
ALSA lib pcm_direct.c:2079:(snd1_pcm_direct_parse_open_conf) Unique IPC key is 
not defined 
aplay: main:830: audio open error: Invalid argument

I'll appreciate any suggestions.

For reference aplay -L lists the following devices.
