Hello,
I have a sound card XONAR DGX which works perfectly with kernel 3.15 and 3.16;
I have KDE installed with alsa, pulse audio seems not active (starting pavucontrol gives “Fatal error. Unable to connect to PulseAudio” )
Since the installation of kernel 3.17 I have the following problem
The card is recognized
# lspci -v | grep -B1 -A12 -i audio
0e:04.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]
Subsystem: ASUSTeK Computer Inc. Device 8521
Flags: bus master, medium devsel, latency 64, IRQ 28
I/O ports at 6000
Capabilities: [c0] Power Management version 2
Kernel driver in use: snd_oxygen
Kernel modules: snd_oxygen
The correct driver is loaded
[size=2]# lsmod | grep snd
snd_oxygen 25132 4
snd_oxygen_lib 45416 1 snd_oxygen
snd_mpu401_uart 14169 1 snd_oxygen_lib
snd_rawmidi 34923 1 snd_mpu401_uart
snd_seq_device 14497 1 snd_rawmidi
snd_pcm 121055 2 snd_oxygen_lib
snd_timer 33609 2 snd_pcm
snd 87947 13 snd_oxygen,snd_timer,snd_pcm,snd_rawmidi,snd_oxygen_lib,snd_mpu401_uart,snd_seq_device
soundcore 15047 1 snd
The card still works but after some time or event the same noise is continuously repeated 1 or 2 times per second
Examples
- Amarok works but if I halt a music then the same sound is repeated 1 or 2 times per second.
The sound device is not freed. If I quit Amarok via the close button a “bip” is produced and the noise stops - The speaker testing fails with this output
speaker-test -c2 -l5 -twav
speaker-test 1.0.27.2
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 2048 to 16384
Period size range from 1024 to 1024
Using max buffer size 16384
Periods = 4
was set period_size = 1024
was set buffer_size = 16384
0 - Front Left
and a noise “fro fro fro” is constantly send out; if I reload Amarok and start a music the noise is stopped and the music plays correctly.
If I halt the music a noise is continually send out but different from the preceding noise. seems that the last send out is continuously repeated 1 or 2 times per second
If i wait that the music ends then no parasite noise
- If I try to see a video in Firefox or Seamonkey then after some times (10-15 seconds) the video stops, the browser is locked and I cannot change to another tab nor close the browser. The same video plays correctly with the kernel 3.16 after reboot
Bug in the sound subsystem with kernel 3.17?
Any Comment?
many thanks in advance
