[alsa-devel] plug:dmix slows playback
by Steve Langstaff 12 Jun '09

12 Jun '09

Hi All. I've got an installation of ALSA (1.0.19 on an embedded device) where using plug and dmix as my output device slows down playback - voices and tones are lower in pitch and the playback takes longer than when not using plug:dmix, e.g. /usr/share/sounds/alsa # time aplay ignition.wav Playing WAVE 'ignition.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono real 0m 3.08s user 0m 0.04s sys 0m 0.07s /usr/share/sounds/alsa # time aplay -D plug:dmix ignition.wav Playing WAVE 'ignition.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono real 0m 6.00s user 0m 0.09s sys 0m 0.08s See how the 'real' time for playing the file goes from 3.08s to 6.00s I have also noticed that the audio is played out of both (L+R) channels when not using -D plug:dmix, but is only played out of the right channel when using -D plug:dmix. I am an ALSA beginner - any ideas where I should start looking? Using the -v option on aplay we get more output... /usr/share/sounds/alsa # aplay -v ignition.wav Playing WAVE 'ignition.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Plug PCM: Route conversion PCM (sformat=S16_LE) Transformation table: 0 <- 0 1 <- 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 8 buffer_size : 4000 period_size : 1000 period_time : 125000 tstamp_mode : NONE period_step : 1 avail_min : 1000 period_event : 0 start_threshold : 4000 stop_threshold : 4000 silence_threshold: 0 silence_size : 0 boundary : 2097152000 Slave: Hardware PCM card 0 'LM4549' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 8000 exact rate : 8000 (8000/1) msbits : 16 buffer_size : 4000 period_size : 1000 period_time : 125000 tstamp_mode : NONE period_step : 1 avail_min : 1000 period_event : 0 start_threshold : 4000 stop_threshold : 4000 silence_threshold: 0 silence_size : 0 boundary : 2097152000 appl_ptr : 0 hw_ptr : 0 /usr/share/sounds/alsa # aplay -v -D plug:dmix ignition.wav Playing WAVE 'ignition.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Plug PCM: Rate conversion PCM (48000, sformat=U8) Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 8 buffer_size : 2720 period_size : 170 period_time : 21250 tstamp_mode : NONE period_step : 1 avail_min : 170 period_event : 0 start_threshold : 2720 stop_threshold : 2720 silence_threshold: 0 silence_size : 0 boundary : 356515840 Slave: Route conversion PCM (sformat=S32_LE) Transformation table: 0 <- 0 1 <- 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 48000 exact rate : 48000 (48000/1) msbits : 8 buffer_size : 16320 period_size : 1020 period_time : 21250 tstamp_mode : NONE period_step : 1 avail_min : 1020 period_event : 0 start_threshold : 16320 stop_threshold : 16320 silence_threshold: 0 silence_size : 0 boundary : 2139095040 Slave: Direct Stream Mixing PCM Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 32 buffer_size : 16320 period_size : 1020 period_time : 21250 tstamp_mode : NONE period_step : 1 avail_min : 1020 period_event : 0 start_threshold : 16320 stop_threshold : 16320 silence_threshold: 0 silence_size : 0 boundary : 2139095040 Hardware PCM card 0 'LM4549' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 32 buffer_size : 16320 period_size : 1020 period_time : 21250 tstamp_mode : ENABLE period_step : 1 avail_min : 1020 period_event : 0 start_threshold : 1 stop_threshold : 2139095040 silence_threshold: 0 silence_size : 2139095040 boundary : 2139095040 appl_ptr : 0 hw_ptr : 0

Re: [alsa-devel] no sound in ubuntu 8.10 on AD1986 sound card
by Daniel Chen 12 Jun '09

Your 'PCM' is muted - is that intentional? Also, unless you're explicitly using digital out, you should mute 'IEC958'. Lastly, if you're using headphones, unmute that element, too.

I do not hear any sound from my speakers. The sound card is AD 1986 (Analog Devices) and it worked wonderfully without any hiccups before on 8.10 and other Ubuntu versions. My alsa-info script is here: http://www.alsa-project.org/db/?f=7f34b4e28d97178d7f709740f91ff66ea08a9468 I suspect pulseaudio is the culprit: Output of : /var/log/syslog | grep pulseaudio is here: http://paste.ubuntu.com/192629/ Running : speaker-test -c2 -D hw:0,0 -t wav -l1 gives no sound. My motherboard is ASUS A8N-VM on a AMD 64 Athlon 3200 Desktop PC.The sound card is detected so no problems there. I have reinstalled ALSA, pulseaudio and all the related packages but to no avail. I am pretty sure this is not a problem of inadeuate support because sound was working before without any issues. Any ideas/suggestions on how to fix this problem will be greatly appreciated. I am also raising an email bug report at alsa-devel so anyone can canter around there and provide expert help :) Thanks, Sandip _______________________________________________ Alsa-devel mailing list Alsa-devel(a)alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel

[alsa-devel] HDA Intel IDT 92HD71B7X - HP Pavilion DV7-1299EF - Subwoofer not Working
by Wael Nasreddine (a.k.a eMxyzptlk) 11 Jun '09

11 Jun '09

Hello, Last night I bought myself a new laptop, the HP Pavilion DV7-1299EF. This laptop has 2 frontal speakers and a subwoofer in the back, on Windows, when I play a sound the 3 speakers works perfectly, and since it has a subwoofer the spearkers hardly has any bass capabilities, On linux the subwoofer is not working, only the 2 speakers are, hence the sound doesn't have any bass and it's loud and annoying, very annoying... I'm using alsa-drivers compiled from today's git checkout.. Here's the snd-hda-intel module options I tried options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=hp-m4 options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=hp-dv5 options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=hp-hdx options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=dell-m4-1 options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=dell-m4-2 options snd-hda-intel enable=1 probe_mask=1 enable_msi=1 single_cmd=0 power_save_controller=0 power_save=0 model=dell-m4-3 Whatever the model option I try, I always end up with only 2 speakers... Here's the alsa-info.sh output -> http://www.alsa-project.org/db/?f=0fd7cb5749b12dd4322879bb3828f9391bfee487 I also attached some more informative files..

Hello all, I was hoping to get involved to fix als bug #305 and related ones, but I see Takashi Iwai has beaten me to it. Awesome. I'd like to test his patch of 5-27 for snd_cs46xx but I haven't done driver development before. How do I test out this patch on my hardware (ThinkPad 600X)? Thanks, Chris
