pactl list was in that file (below aplay aoutput) http://pastebin.com/NnDvQ2kU Even if line in capture is on there is now difference. >You have to ask the author of snd-emu10k1 as I only know how to use devices in the above conf Hmm. Now I think is not worth trying. I give up and I will buy a new sound card. This will be the best solution here. Anyway thank you for your commitment. I'm really impressed with your great attitude and knowledge. 2014-11-24 7:05 GMT+01:00 Raymond Yau <superquad.vortex2 at gmail.com>: > > > >http://pastebin.com/NnDvQ2kU > > > > :~$ aplay --dump-hw-params -D surround40:CARD=Live > /usr/share/sounds/alsa/Front_Left.wav > > appropriate number of channels is not available WAVE > '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, > frequency 48000 Hz, Mono > > HW Params of device "surround40:CARD=Live": > > -------------------- > > ACCESS: MMAP_COMPLEX RW_INTERLEAVED RW_NONINTERLEAVED > FORMAT: U8 S16_LE > SUBFORMAT: STD > SAMPLE_BITS: [8 16] > FRAME_BITS: [32 64] > CHANNELS: 4 > RATE: [4000 96000] > PERIOD_TIME: (166 8192000] > PERIOD_SIZE: [16 32768] > PERIOD_BYTES: [64 262144] > PERIODS: [1 1024] > BUFFER_TIME: (666 8192000] > BUFFER_SIZE: [64 32768] > BUFFER_BYTES: [256 262144] > TICK_TIME: ALL > -------------------- > > Both hw and front (mono and stereo profile) support MMAP_INTERLEAVED and > RW_INTERLEAVED BUT surround40 and surround51 support MMAP_COMPLEX or > RW_INTERLEAVED > > 44100Hz is supported but disabled when pulseaudio use no resample > > Seem bug or limitaion of multi plugin when the slaves does not support > RW_NONINTERLEAVED > > Do pulseaudio expect all profiles of the sink or card use same access > type ? > > Seem no way to force pulseaudio to try RW_INTERLEAVED first since > udev-detect only has tsched flag > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/module-udev-detect.c > > What is the purpose of bool *use_mmap in pa_alsa_set_hw_params when user > are not recommended to use module-alsa-sink indefault.pa > > int pa_alsa_set_hw_params( > snd_pcm_t *pcm_handle, > pa_sample_spec *ss, > snd_pcm_uframes_t *period_size, > snd_pcm_uframes_t *buffer_size, > snd_pcm_uframes_t tsched_size, > bool *use_mmap, > bool *use_tsched, > bool require_exact_channel_number) { > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/module-alsa-card.c > > "mmap=<enable memory mapping?> " > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/module-alsa-sink.c > > "mmap=<enable memory mapping?> " > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/module-alsa-source.c > > "mmap=<enable memory mapping?> " > > > > >Do pactl can select the capture source? > > > > I don't know what specific command shold I use. > > > > pactl --help > > You have to post output of > > pactl list > > Capture source is not a mixer element but a hctl control > > control.64 { > iface MIXER name 'Capture Source' > value.0 Mic > value.1 Mic > comment > { access 'read write' > type ENUMERATED count 2 > item.0 Mic > item.1 CD > item.2 Video > item.3 Aux > item.4 Line > item.5 Mix > item.6 'Mix Mono' > item.7 Phone } } > > Those mixer elements with " Capture exclusive group: 0" are belong to > "Capture Source" control > > cswitch-exclusive mean only one of the source can be switch on within > capture exclusive group > > Simple mixer control 'Line',0 > Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-exclusive > Capture exclusive group: 0 > Playback channels: Front Left - Front Right > Capture channels: Front Left - Front Right > Limits: Playback 0 - 31 > Front Left: Playback 31 [100%] [12.00dB] [on] Capture [off] > Front Right: Playback 31 [100%] [12.00dB] [on] Capture [off] > > To select line in as capture source, you need to set the line capture > switch on > > those mixer elements with "pswitch-joined" have input to ac97 analog mixer > > you have to switch on line playback volume and switch if you want tv > card output sound through line in of ac97 mixer to the front line out > > Pcm playback volume/switch with pswitch-joined is also an input to ac97 > analog mixer > > Simple mixer control 'PCM',0 > Capabilities: pvolume pswitch pswitch-joined > Playback channels: Front Left - Front Right > Limits: Playback 0 - 31 > Mono: > Front Left: Playback 23 [74%] [0.00dB] [on] > Front Right: Playback 23 [74%] [0.00dB] [on] > > You need to select stereo mix if you want to capture from mix of line in, > mic, pcm.... and change those source playback volume and switch > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths > > Is "pactl set-source-port" the correct command to set capture source > control if pulseaudio does not save and restore the selected source port of > the default sink for those sound cards with ac97 codec > > > http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa/alsa-mixer.c?id=300a5e3ed70064c296e09bc4e40531f3257154c5 > > > > Which devices do you want to use?
