I got a set of instructions from Reuben Firmin at flavor8, and I followed them to the best of my ability. I asked him what might be the problem, and he said it looked OK to him, but unfortunately it doesn't work. He suggested I try asking the folks at this mailing list.
The original url was http://flavor8.com/index.php/2007/01/14/how-to-easily-switch-soundcards-in-linux/ I'm running PCLINUXOS kernel 2.6.33.7-pclos6.bfs, with kde 4.6.2. Here's what I did, and where the problem must be: First, I substituted TRI for usb and SiS for desktop in all the files, these being the initial letters of the two sound devices (SiS is on the mobo, TRI is a plug-in card). Next I entered the first script into a new file in /etc called asound.conf. Then I made a directory called /sound under /usr, and created the second two files in it, called, respectively, .asoundrc_SiS and .asoundrc_TRI. Finally, and here's where I think the problem lies, I changed directory to /bin and entered the two files in it as alsa_TRI and alsa_SiS. Since these were apparently script files, I made the heading on each of them read #!/bin/bash. (Nothing would access them if they were just text files.) I thought that /bin usually held binary files, not scripts. Is _that_ the problem? If so, where should the scripts be? Finally, I made icons pointing to the two script files. Here are the actual files: [doug@localhost ~]$ cat /etc/asound.conf pcm.TRI { type hw card 1 device 0 channels 2 } pcm.SiS { type hw card 0 device 0 channels 2 } pcm.!default { type plug slave.pcm "SiS" [doug@localhost ~]$ cat /usr/sound/.asoundrc_SiS pcm.!default { type plug slave.pcm "SiS" } [doug@localhost /]$ cat /usr/sound/.asoundrc_TRI pcm.!default { type plug slave.pcm "TRI" } [doug@localhost /]$ cat /bin/alsa_TRI #!/bin/bash cp /usr/sound/.asound_TRI ~/.asoundrc [doug@localhost /]$ cat /bin/alsa_SiS #!/bin/bash cp /usr/sound/.asoundrc_SiS ~/.asoundrc I have sound coming from the SiS card, regardless of clicking on the TRI icon. (I have shutdown firefox, and then reopened it.) I test this with a radio-station playing on the internet. I have speakers on the SiS card, and headphones and a mic on the TRI card. Reuben did suggest I remove default from the 'asoundrc_*** files; if I were to do this, how would the line read? aplay -l yields this: doug@localhost /]$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SI7012 [SiS SI7012], device 0: Intel ICH [SiS SI7012] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: TRID4DWAVENX [Trident TRID4DWAVENX], device 0: trident_dx_nx [Trident 4DWave] Subdevices: 32/32 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 Subdevice #8: subdevice #8 Subdevice #9: subdevice #9 Subdevice #10: subdevice #10 Subdevice #11: subdevice #11 Subdevice #12: subdevice #12 Subdevice #13: subdevice #13 Subdevice #14: subdevice #14 Subdevice #15: subdevice #15 Subdevice #16: subdevice #16 Subdevice #17: subdevice #17 Subdevice #18: subdevice #18 Subdevice #19: subdevice #19 Subdevice #20: subdevice #20 Subdevice #21: subdevice #21 Subdevice #22: subdevice #22 Subdevice #23: subdevice #23 Subdevice #24: subdevice #24 Subdevice #25: subdevice #25 Subdevice #26: subdevice #26 Subdevice #27: subdevice #27 Subdevice #28: subdevice #28 Subdevice #29: subdevice #29 Subdevice #30: subdevice #30 Subdevice #31: subdevice #31 card 1: TRID4DWAVENX [Trident TRID4DWAVENX], device 2: trident_dx_nx IEC958 [Trident 4DWave IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 -- Blessed are the peacekeepers...for they shall be shot at from both sides. --A.
