[alsa-devel] Changing default card using its name
by Pavel Hofman 23 Nov '10

23 Nov '10

Hi, Please excuse my ignorance but I have not been able to figure out this simple task. Nowadays most PCs have multiple soundcards (onboard plus HDMI, often another PCI card). Order of the cards is not stable. How do I define in /etc/asound.conf another default card using its name and keep the PCMs defined by its corresponding alsa card/pcm config files? In my case aplay -L: null Discard all samples (playback) or generate zero samples (capture) front:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog Front speakers surround40:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Intel,DEV=0 HDA Intel, STAC92xx Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=NVidia HDA NVidia, NVIDIA HDMI HDMI Audio Output front:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI DAC/ADC Front speakers rear:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC Rear speakers surround40:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC 4.0 Surround output to Front and Rear speakers surround41:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI 2nd DAC 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=CMI8768,DEV=0 C-Media CMI8768, C-Media PCI DAC/ADC IEC958 (S/PDIF) Digital Audio Output Is it actually possible to have iec958:CARD=CMI8768,DEV=0 as the system-wide device iec958? I have not been successful with defaults.ctl.card "CMI8768" which IMO would have been the simplest solution. Thanks a lot for help. Regards, Pavel Hofman.

Re: [alsa-devel] nvidia initial sound being skipped

Hi All, I just want to say I upgraded to kernel 2.6.36 today and still miss the first 0.5seconds or so of the sound output. Again I have ruled out player - mplayer, aplay and audacious all do it I have ruled out source format - both flac and the wav decoded version have the same problem. I have also ruled out physical connection to the AVR, both HDMI and SPDIF exhibit the same problem. Any ideas?

[PATCH 2/2] alsactl: systemd and udev hookup
by Lennart Poettering 23 Nov '10

23 Nov '10

Add minimal systemd and udev support to alsactl so that mixer settings are restored at boot, when sound cards are plugged in and saved on shutdown. This is similar to existing udev/init script solutions in various distributions. Note that alsactl is called both synchronously from the udev rules as well as asynchronously at boot. This is intended, and to ensure two things: - At boot the asound.state file might not be readable, since it resides on a different file system. That means exclusively restoring sound card settings from udev rules will no suffice, since if the rule is executed at early boot (for example within udev settle) then the file will no be readable and cannot be restored. - We need to ensure that applications monitoring sound cards coming and going (such as PA) must not get these events before the mixer settings have been restored. That means the mixer settings must be restored synchronously withing the udev rules, before the events are passed on to the apps. That basically means we need to restore the settings once in udev, to deal with sound cards becoming available during runtime. And once in early boot to deal with coldplugged soundcards whose data files might not have been available at time of plugging. Hence we call alsactl twice: one from the udev rule, and once from he systemd unit file. --- Makefile.am | 3 ++ alsactl/.gitignore | 3 ++ alsactl/90-alsa-restore.rules.in | 2 + alsactl/Makefile.am | 46 ++++++++++++++++++++++++++++++++++++++ alsactl/alsa-restore.service.in | 11 +++++++++ alsactl/alsa-store.service.in | 9 +++++++ configure.in | 17 +++++++++++-- 7 files changed, 88 insertions(+), 3 deletions(-) create mode 100644 alsactl/.gitignore create mode 100644 alsactl/90-alsa-restore.rules.in create mode 100644 alsactl/alsa-restore.service.in create mode 100644 alsactl/alsa-store.service.in diff --git a/Makefile.am b/Makefile.am index 9951c46..62e1ba6 100644 --- a/Makefile.am +++ b/Makefile.am @@ -37,3 +37,6 @@ dist-hook: else \ $(TAR) --create --verbose --file=- $(distdir) | bzip2 -c -9 > $(distdir).tar.bz2 ; \ fi + +DISTCHECK_CONFIGURE_FLAGS = \ + --with-systemdsystemunitdir=$$dc_install_base/$(systemdsystemunitdir) diff --git a/alsactl/.gitignore b/alsactl/.gitignore new file mode 100644 index 0000000..56ab3a2 --- /dev/null +++ b/alsactl/.gitignore @@ -0,0 +1,3 @@ +alsa-store.service +alsa-restore.service +90-alsa-restore.rules diff --git a/alsactl/90-alsa-restore.rules.in b/alsactl/90-alsa-restore.rules.in new file mode 100644 index 0000000..0bcee5b --- /dev/null +++ b/alsactl/90-alsa-restore.rules.in @@ -0,0 +1,2 @@ +ACTION=="add", SUBSYSTEM=="sound", KERNEL=="controlC*", KERNELS=="card*", \ + RUN+="@sbindir@/alsactl restore $attr{number}" diff --git a/alsactl/Makefile.am b/alsactl/Makefile.am index 359f73a..9a2d30e 100644 --- a/alsactl/Makefile.am +++ b/alsactl/Makefile.am @@ -10,5 +10,51 @@ EXTRA_DIST=alsactl.1 alsactl_init.xml alsactl_SOURCES=alsactl.c state.c utils.c init_parse.c noinst_HEADERS=alsactl.h list.h init_sysdeps.c init_utils_string.c init_utils_run.c init_sysfs.c +udevrulesdir=/lib/udev/rules.d + +dist_udevrules_DATA = \ + 90-alsa-restore.rules + +if HAVE_SYSTEMD + +systemdsystemunit_DATA = \ + alsa-store.service \ + alsa-restore.service + +install-data-hook: + $(MKDIR_P) -m 0755 \ + $(DESTDIR)$(systemdsystemunitdir)/basic.target.wants \ + $(DESTDIR)$(systemdsystemunitdir)/shutdown.target.wants + ( cd $(DESTDIR)$(systemdsystemunitdir)/basic.target.wants && \ + rm -f alsa-restore.service && \ + $(LN_S) ../alsa-restore.service alsa-restore.service ) + ( cd $(DESTDIR)$(systemdsystemunitdir)/shutdown.target.wants && \ + rm -f alsa-store.service && \ + $(LN_S) ../alsa-store.service alsa-store.service ) + +endif + +edit = \ + sed $(SED) -r 's,@sbindir\@,$(sbindir),g' < $< > $@ || rm $@ + +alsa-store.service: alsa-store.service.in + $(edit) + +alsa-restore.service: alsa-restore.service.in + $(edit) + +90-alsa-restore.rules: 90-alsa-restore.rules.in + $(edit) + +EXTRA_DIST += \ + alsa-store.service.in \ + alsa-restore.service.in \ + 90-alsa-restore.rules.in + +CLEANFILES = \ + alsa-store.service \ + alsa-restore.service \ + 90-alsa-restore.rules + %.7: %.xml xmlto man $?

[alsa-devel] dell m4500 precision alsa-base.conf
by Adam Hamer 22 Nov '10

22 Nov '10

After searching on why my m4500 couldn't use the microphone I found out all the stuff about alsa. 1) A few web pages state 'let us know' if you find a configuration that works for your machine....but IT DOESN'T SAY WHO TO TELL! eg Reporting Problems in http://www.alsa-project.org/main/index.php/Help_To_Debug_Intel_HDA and http://www.alsa-project.org/main/index.php/Help_To_Debug 2) Anyway, I have those details for the m4500 so I am posting them here. This fix solved my internal microphone not working.I added 'options snd-hda-intel model=dell-s14' to the alsa-base.conf. I didn't try many others. I attach the files which are meant to be helpful for someone! Regards,adam

[alsa-devel] HDA Analyzer - Dell M4500 Internal Mic

22 Nov '10

Hi all! My mic didn't work (Dell M4500) . Using HDA Analyzer I create a configuration that does work. I read that I could send my working codec to here. So here it is. Maybe you can also tell me how te make this change permanent?
